Leak Detection Tools.

[Pascone10]

Ok guys im looking for your advice and mainly your experience.

Today I was working on a roof, 120v not close by, looking for a refrigerant leak.

I have the POS CPS Eliminator (the yellow one). The damn thing wound not stop ramping off all the place. No leaks in sight. SO now im through with this thing..

I own the h-10G from your recommendations. However I want something portable.

WHat do you guys think? I've been searching ultrasonic and the reviews are so mixed. What has your experience been? Also whats a good battery powered unit?

[rmuntz]

The H-10's were good in their day but technology is outdated now. I prefer the Infinicon leak detector now, pricey but reliable.

Why not just get a H-10PM and a D-tek? From what I hear......money's no object for you and Nick.:whistle:

I'm a bit jealous of you guys.:grin2:

[coolperfect]

Here we go again,the only threads that beat leak detector count are,union vs non union,nitro vs no nitro, Ford vs Chevy!

I would not go that far. I think it is safe to say I have a problem. Hell, The first step to recovery is admitting it right..

But then again you have to want to change and well, Lets say Im not there yet lol..

Nick is not all that happy with his inficon D tek and whatever you do, dont bring up the Pilot in front of him! THat why I'm not sure if I should go that route. Im replacing the last of the cheap tools I bought when I was starting out and this CPS is one of them.. So, CJ do you have an advice to offer or what? :cheers:lol

Lol.....my pilot is 5 years old now. And my go to leak detector is the first gen d-tek.

[Pascone10]

oh, boy..:gah:

[coolperfect]

Fieldpeice IR,D Tek,some good luck!

[ascj]

oh, boy..:gah:

It's very rare, I even bust out the leak detector. I'm normally can find the leak visually and verify location with bubbles.

I had to bust out a detector twice this year. One was a YCAL that was low on one circuit. No visual. Detector(D-Tek) went off at relief valve. Long story short.....found out the chiller got hit with boiler water this last winter. Other was a Smardt chiller. Detector(H10-G) found fitting on barrel leaking.

How do you like that Fp? Im Not a fan of FP usually. WHich do you like better?
Thanks for the replies..

BTW Do you drive a Ford or a Chevy? Chevy's Kick A**..

JK seriously tho, I appreciate your opinion..

[coolperfect]

Like both,also liked the Tif zx1 till It fell off a ladder. Chevy Z/28 and van!

:gah::beat: i hate that darn thing, pos imo. As far as the leak detector it has worked, my main gripe with it is the battery, absolutely horrible, every time i take it out its dead!!! but it has found a leak or two that was unable to be found with other leak detectors, including your CPS....:whistle:

[Pascone10]

Maybe I'll look into that fieldpiece slr2. Mechacc made a few videos with it. Looks like it does a fine job. There was just something about standing 5' away from the unit and finding the leak that was appealing to me!

[itsiceman]

You got anything to trade for a SRL2 Pascone10
My high light is broke but other than that it works like it is supposed to.
I only use it when the ZX-1 battery goes dead.

[Pascone10]

Hmm not really. Just starting out with tools. Not much on the extra side o things. Doesn't the zx1 drive you crazy when you bump the probe? What's your suggestion for a good detector?

[coolperfect]

What I liked about the zx it would Pick up leaks far away.I would than switch to my other dectectors to home in.I always bring all I got on a job,to help find the leak,and to see which one does better on any given job,and to know they are all still up to snuff.

That was the ZX-1

[Pascone10]

That was the ZX-1

Standing away i was refeering to the Ultrasonic. I didn't seethe zx do that in your video. When you were comparing the FP and the ZX1 that looked similar to me. What say you. If anyone's opinion counts it's yours! Thanks.

[MechAcc]

The ZX-1 5 feet away was the first time I used it (no video) on a Trane residential condenser. Had to get right up next to the case with D-Tek Select. Both were set on high sensitivity.

Hmm not really. Just starting out with tools. Not much on the extra side o things. Doesn't the zx1 drive you crazy when you bump the probe? What's your suggestion for a good detector?When that happens to me something is dirty.....tip, filter, wand
The ZX-1 has been great for me.
The SRL8 is also very nice
I wouldn't buy the SRL2 again for the extra cost.

anyone seen this? looks expensive !

[ascj]

oh, boy..:gah:

My Pilot took a crap yesterday. You and Nick jinxed me.

Have a BluVac on the way.

Nice! Let me know what you think. I Have not used it at work yet. Some guys apparently don't use micron gauges:Faint: lol..

So do I go Infrared leak detector or something else. I have that H10..
Or should I look at Ultrasonic.

Im almost looking sleep on what way to go.. Well not really but it sounded good.

[EugeneTheJeep]

I just picked up this new Infrared Robinair 22791 on FLEABay, I will let you know how it works out. Supposed to be up to the latest and greatest standards. Seem that Infrared is the way to go now a days?

That looks a lot similar to the fieldpiece. I think im going to pick one up. DOes that come with all the cool attachments?

[EugeneTheJeep]

It looks exactly like the Fieldpiece, I am sure it is the same. And I was going to grab one of them just the same.

Comes with a case, magnetic holder, extra filters and 0 rings, AC and DC chargers.

[Pascone10]

http://fieldpiece.com/leak-a-gas-detectors/srl2k7

I like the Fieldpiece because of the small tips and extra length attachments that come with it..

Plus fieldpiece customer support is nice. It's nice to see russell on here helping the guys out. Although I did call him and left a message. We will see of he calls me back..

Why didnt you just go with the name brand?

[ault51]

Just FYI, it may look the same but the sensitivity is not. The non fieldpiece version is for the automotive ac industry. The auto industry has different regulations on leak detectors than regular hvacr. The auto industry leak detector standards don't allow leak detectors to be as sensitive as the leak detectors you guys use. The non fieldpiece version is not as sensitive as the fieldpiece version so that it can be sold to the auto industry.

Bottom line, the case (plastic) is the same, the guts are not.

[hvacrmedic]

The ZX-1 5 feet away was the first time I used it (no video) on a Trane residential condenser. Had to get right up next to the case with D-Tek Select. Both were set on high sensitivity.

The IR detectors operate differently, and require different methods. They sense changes in refrigerant vapor concentration rather than refrigerant concentration per se. IOW, you have to keep it moving. It will auto-reset to the ambient level. That's a plus, not a minus, due to the particular mode of operation of the detector. It allows fast and precise pinpointing of leaks with no fiddling around with the buttons.

Actually the Robinair is more sensitive. :whistle:

http://www.fieldpiece.com/standalone-instruments/srl2k7

http://www.ntxtools.com/network-tool-warehouse/ROB-22791.html

They both meet SAE J2791 leak detection standard.

[itsiceman]

Actually the Robinair is more sensitive. :whistle:

You might want to reread that :whistle:
Also does the Robinair have the turbo mode like the F/P?

[EugeneTheJeep]

You might want to reread that :whistle:
Also does the Robinair have the turbo mode like the F/P?

1/15th is more sensitive then 1/10th, as well as 1/2 is more sensitive then 1.

Yeah, it has the peak button that you push 4 times for turbo mode. Watch at 6:40 http://www.youtube.com/watch?v=GA9A7cUWRHI

Does the FP have a hidden turbo button?

So how is your SRL2(K7) working for you?

Kind of retarded for any one to think these are so much different? :deadhorse:

My GMC is better then your Chevy :gah:

Sorry I forget the Yellow case makes it better, especially if you are brand loyal to FP tools with their LCD displays that wont work below 20 degrees. :grin2:

[itsiceman]

Waiting for something to click ....... :couch:

[Pascone10]

ICE your funny..

Eugene Those accuracies are in sensitivity to a leak rate in ounces...

So .1 is a smaller leak then .15oz

Now MAYBE the FP is the same and they just left off the 5 lol:bump:

[itsiceman]

FWIW The newer UEi RLD15 and J/B Prowler LD5000 are listing sensitivities of
0.05 oz/yr for R-410A and 0.025 oz/yr for R-22

OK guys, you got me, I give up. But why is the Robinair more sensitive at low then the FP?

[Pascone10]

Maybe ill look into that JB. Its made in the USA.

I have no clue about that elctrochemical sensor tho. Kinda makes me nervous trying something new...

[texas2golfer]

I have used the MARS H10PM with very good success. It is a little pricey at around $400 if my memory serves me. It has a chargeable battery. It is very accurate.

Features and Benefits:

* Built in battery
* Detects all CFC, HFC and HCFC refrigerants
* Unique sensor calibration system
* Pinpoints large and small leaks
* Manual and automatic sensitivity adjustment
* Heated diode technology

[itsiceman]

It says two year warranty including the sensor for the J/B

Three year including the sensor on the UEi

I don't think you would be impressed by the F/P I/R other than its easier to operate and more convenient than your H10

If you want better I think you'll have to try something new :.02:

WFIW I didn't care for the look or feel of the J/B but I like the bar graph vs the numbers on the UEi

[74apollo]

I have the inficon Dtek Select and it has been very good to me

[darctangent]

I have the Johnson Controls RLDH-10PM, the Infocon Detec Select, and have used the old CPS, TIF, and the First gen Infocon Detec.

Additionally I own a CTRL 101 ultrasonic.


The Detec select is fairly responsive but is annoyingly fast in it's auto correct to ambient refrigerant levels. When it dampens it's response it should have a second bar graph to tell you how much it is choking off it's sensitivity. Rhat way you know what it's doing when and it would tell you when it goes back to normal too. If you combined that with it's propensity for false alarms from fast movements or air streams the Select come across as flaky even if it really isn't.

Not so with the H-10PM It is highly sensitive without false alarms. It also allows you to adjust the sensitivity to your liking and to be aware of how the unit is set, unlike others where you must accept the programming from the MFG even when you have no clue what it's doing! Just because the H-10 is old and looks outdated you would be wise to not discount it. The H-10PM is one fine leak detector.

It should be noted that the H-10's require maintenance, but they are entirely field serviceable from what I have seen. Parts are available online and the battery is easily obtained locally. It is a common lead acid sealed battery.


I really like my CTRL 101, but it's still new to me. I have experimented with it and so far I have only been able to detect leaks that had bubble solution or at least water or some other liquid. When that is the case the leak will light up the detector like a Christmas tree. Another benefit of ultrasonic is that is HIGHLY, HIGHLY directional. There are basically no phantom readings. If you can hear the leak you are pointed at it!

[Pascone10]

Thanks agent. That was good advice. I was just looking for something portable. I suppose I should have went with the pm. For now I'll use the cord lol. I hate false alarms. I had that problem using my bros tif.

How much was that ultrasonic. Looks expensive

[itsiceman]

From the last two days I'm two for two with my old Amprobe but they were big leaks. Got one right thru the insulation from three feet away.
I'm gonna order the AccuTrak VPE since I've used one and they are much better than the Amprobe I have and will let you know how it goes with some smaller leaks.

I just saw the VPE in ACHR News. Yea let me know what you think. Maybe ill give ultrasonic a Shot... How much is the VPE?

[itsiceman]

I've seen a big range on those.
Seen 280 on the low end. Hundred more at other places :confused:

Why doesn't all the manufactures make a ultrasonic leak detector?

Have you ever tried to use one Pascone?

If not I can probably get one to you to try out. I think I have some laying in my father's old shop.

Ultrasonic's are all about hearing the leak.....so they work better when it's quiet. Hmm.....good luck with that. Also, wind makes noise. Hmm.

I got to ask Pascone.....what are you looking for? The perfect machine to find any leak you encounter? I would say there is no such thing.

My best advice is to focus on what leaks you weren't able to find and what you could have done to find them. Most of the time it's you weren't able to access or it was to difficult to access the area you really needed to check.

I'm not trying to knock anyone, but I just can't see a decent sniffer, a bottle of bubbles, and the will power to look at every joint......not finding a leak.

Maybe I have been lucky?

Well you are the man CJ!

I started this thread looking for a cordless unit (open to ideas on the technology) to supplement my H10. I like the H 10 a lot I just wanted something good and battery operated. The biggest thing is I dont want junk. The battery powered CPS Sucks!

SO that about sums it up. Just looking for something to add to the arsenal. I wanted to hear from the guys that use them and their recommendations..

BTW that accutrak is not supposed to be influenced by wind.

Maybe I have been lucky?The VPE is hardly affected by ambient. I've used it a few times. I guess it still is affected by Fluorescents per a few guys here but you can still hear the difference between a leak and a light unlike other Ultrasonics.
They say the more expensive unit is even better but I'm not dropping that coin on one. They say get a good set of headphones and you'll be in good shape with the VPE.

[itsiceman]

BTW that accutrak is not supposed to be influenced by wind.
This is one of the main reasons I'm getting one over another electronic. It will be better on a a windy roof.

You know the expression... If you have to ask... LOL


The truth is that I couldn't afford one either, so when I met a guy with one I had to kill him in order to get it.

The basic kit starts at about $2500 as I recall.

[itsiceman]

CTRL Systems has some videos here

http://www.youtube.com/user/CTRLSystems#p/u/1/iHEpHLwCvAE

darctangent have you used a VPE?
From the CTRL videos they seem similar to me but a fraction of the cost.

Sorry iceman, I can't prove or disprove that. I can't comment beyond what is apparent by looking at it. The VPE has an adjustable probe, the VPE has numerous attachments depending on the application.

If the VPE can overcome the advantage that the CTRL 101 has in general design through better pick up and filtering then I guess it's possible that the VPE is comparable.


Time will tell.

[darctangent]

darctangent have you used a VPE?


Iceman, is the the same unit you are talking about?

http://www.reliabilitydirectstore.com/VPE-Ultrasonic-Leak-Detector-p/sup-vpe.htm

If so I have seen it, or an earlier version of it, but sold as a different brand name. I THINK it was a robinair product. The product rep wasn't willing to make any grandiose claims regarding it.

If it's the same thing that I saw ten years ago, I would think that the CTRL 101 would slice and dice that thing.

I guess there were some knock offs a while back that may have infringed on their patent and are no longer around maybe it was just a simple rebranding deal that went to the way side I don't know. I thing MecAcc has one by a different name but he also has the VPE-2000 I think.

First indication? .....Hell no.

You will need to adjust your concept that cheap and reliable fit in the same sentence when buying tools. Some times it works out that way, but most of the time it doesn't! What are you doing worrying about buying a leak detector for anyway? There are plenty of other basic tools you should worry about first.


It's an old saying among tradesmen, but it will always be true:

When buying tools, buy the best that you can reasonably afford, because the best will last a lifetime.


The duck has spoken.

[EugeneTheJeep]

So far so good with my new Robinair 22791. I love the fact that it finds leaks, and does not false alarm if I bump it on something.

I wouldn't mind trying that model at all. Generally I would get the fieldpeice because as others have said, I like their support and Russel is here on HVAC-TALK. It's obviously the same design. I'm not totally sold on fieldpiece, but they do many things right.

I meant reasonable and reliable.i know cheap tools usually are crap. Looking to spend around 200.I have tools to do the job, but I need to start getting more tools to do different jobs. What other basic tools? We don't like to charge systems without searching for leaks first...

I may be wrong about MechAcc having the VPE-2000 that one looks new. Mech?

http://www.superiorsignal.com/accurevw.pdf

and I see a new model? VPX-WR
Waterproof!
20kHz-1000kHz
No tuning

Anyway looks like the VPE and VPE-1000 might use the same air sensor 36kHz-42kHz but it adds a second dedicated sensor for surface detection 18kHz-22kHz

You the one with the dirty ZX-1 Jeep :grin2:
The I/R will false alarm in turbo mode and will pick up differences in CO2 level.

Being that you are new here, and in the trade, do you know HOW to find out if the system needs a charge? hint- generally SH & SC.

First, your post is much broader than this thread, you should start another of your own.

Second, (to be addressed in your own thread), you should address your need for tools according to what work you need to do and who else you work with and what tools they have. This will change over time, but it can ease your burden somewhat. Hand tools are your first priority. Your boss should be able to give you some kind of assistance in getting geared up. I have over $10,000 in tools, but I could squeak by on maybe 2-3k, but even that is hard for a new guy to buy at once. FYI, the fieldpiece SLR2 looks fairly decent for the price. Should last a while too. don't toss your money on a crappy leak detector, you will be pissed, and waste your time too. The ultrasonics being discussed here are not a first line of leak detection, IMO. Good electronic followed by a bubble leak indicator is the general consensus.

[itsiceman]

The SRL8 is just over two bills
Not 2crappy either
Better than decent for the price compared to the SRL2

Being that you are new here, and in the trade, do you know HOW to find out if the system needs a charge? hint- generally SH & SC.

First, your post is much broader than this thread, you should start another of your own.

Second, (to be addressed in your own thread), you should address your need for tools according to what work you need to do and who else you work with and what tools they have. This will change over time, but it can ease your burden somewhat. Hand tools are your first priority. Your boss should be able to give you some kind of assistance in getting geared up. I have over $10,000 in tools, but I could squeak by on maybe 2-3k, but even that is hard for a new guy to buy at once. FYI, the fieldpiece SLR2 looks fairly decent for the price. Should last a while too. don't toss your money on a crappy leak detector, you will be pissed, and waste your time too. The ultrasonics being discussed here are not a first line of leak detection, IMO. Good electronic followed by a bubble leak indicator is the general consensus.



Yes, I am aware of how to charge. I realize I look like a complete noob on the forum, but I went to a very good trade school and have charged many systems before. But my new employer requires we buy our own tools. I have the basics, just trying to buoild up my inventory. Thanks for the help. Ill start my own thread if needed

Did we determine which detector has most positive reviews in this thread?

Not yet... I'm more confused then when I started lol..

Im sticking with the H10 until ice tells me how he likes the ultrasonic. If no go I may go with the slr2 for $400 bucks. Curious about the other technology..

Then again I lay look at that tif...

[EugeneTheJeep]

You the one with the dirty ZX-1 Jeep :grin2:
The I/R will false alarm in turbo mode and will pick up differences in CO2 level.

No comprendie amigo? You must be reffering to another thread. But that ZX-1 is a total POS, has more time on mail order repair, then OTJ.

But so far the IR has found every leak I have seeked, and I still do not know how to use it 100%. I have to read the book as I go, I guess?

Fieldpiece

better accessories, better support.

I really, really like the second bar graph telling you that the unit is dampening it's response. It would make my Infocon a much better detector.

I recently bought a Bacharach Informant 2. You should check it out! I am very happy with it. It found a 410a leak that I had been looking for that 2 other techs from different companies had searched for before me. As far as Field Piece goes... It got its name because the Piece of Sh*t falls apart inf the field! Don't buy them... You'll regret it very soon!

You have any of the Fieldpiece detectors that fell apart or did you have a bad experience with something else they make?

I agree with you. Never heard FP was a POS.. I'm not crazy over some of there meters because I like Fluke but I know far more FP lovers then fluke nowadays. Mainly because of upfront cost.

Did we determine which detector has most positive reviews in this thread? That has not happened in the last 5 years,no difference in this thread !

[deon]

I have a d-tek compass and love it .In fact I got anothher to have for back up .
I have found leaks with it that could not be found with the Yellow Jacket,or Tif or Fieldpiece. I think I paid about $250 for the compass.

[energy star]

I guess we all need to buy two or three.

[marvin]

the last few weeks ive been using the accu trak vpe more
ihan usual & having very good results. i found one in a line
set about 2 inches behind the stucco & when we opened the
wall the leak was within a couple inches of where we were hearing
it the best. this leak was about 3 lb. a year on a 15 # charge
system & had been leaking about 10 years.

The tools forum is open to the non pro's as well. Even though it's in the pro section it is open to the public.

Thus spake the Duck.

[Painful Chafe]

The H-10's were good in their day but technology is outdated now. I prefer the Infinicon leak detector now, pricey but reliable.

???????????????????????????????????????????????

Really what makes you say this. Have you A/B'd an H10 to anything else on the market?

All Pro Areas should be closed to the general public. They do not use are tools.

As you can tell, I'm a Fluke guy but I use Tif ZX-1 detectors. I'll gladly put my ZX-1 up against the FP finding a One bubble leak. The Robinair might be OK but their Customer Service is POOR.

You FP guys can't take any Joking.

I just replaced my ZX-1 with the Robinair. The ZX-1 was pathetic at leaks and spent most of its time being shipped to the mfg for repair. I am not so sure of the Robinair, it is new, and I hope for the best.

BTW I don't like FP meters, I use Fluke as well, but the only difference between the Robinair and the FP leak detector is the color of the case.

[DOGBOY]

but what about picking up 410-a leaks? what are you guys finding to work on the smaller leaks? my h-10 works wonderful on r-22 but 410-A it is questionable at times.

[itsiceman]

My last 410 leak was small.
My ZX-1 found it.
My SRL2 did not trigger.
I like the F/P unit as back up when my ZX-1 battery goes dead though.

[MechAcc]

Questions to the folks having troubles with their detectors.

How often do you change tip filters?

Do you check, and in the case of the H-10 calibrate, your detector against a reference leak?

Do you allow the sensor to clear out before turning it off?

[itsiceman]

My ZX-1 filter is dirty

I have a 11 year old Fieldpiece HS26 "stick" meter. It has spent it's entire life in my tool bag, in the rain, snow, temp from 0 degrees up to 130. It is used several times a day and I never had an issue with it. Not once. I have also used a SC76 for 5 years without any issues.

Try the SRL2K7 infrared unit. No heated diode replacement or worry about if it's getting weak over time. Very sensative unit. the ZX1 is nice too but I'll stick with the FP.

[itsiceman]

I try it all the time Rcb
The SRL2 is the detector the SRL2K7 is the number for the kit with the attachments, box and extra filters

The tools section is what brought me to this site. I was looking for reviews on a couple things and found this. I've been in the field for 10 years so I'm not the general public.

Unless Eugene has used any other I/R detectors than the one he just bought he is probably just repeating what some sales guy has told him.

I've used D-TEK Select and the Fieldpiece I/R
The D-TEK was not so great when it first came out but sounds like they made improvements and probably works as good as the F/P now.

Both those I/R detectors and the ZX-1 list .1 oz/yr for r-410a

Those newer J/B and UEi detectors mentioned earlier are rated with a sensitivity of .05 oz/yr for r-410a and they are not I/R

What a hypothesis you make of me? I am not sure if you are trying to just discredit me or what? I did not talk to a salesman, I just did a search for Infrared detectors and the Roinair was on the list. Eugene just so happens to own a D-Tek Select, and I am not pounding my chest for the Robinair, just made mention I bought it, and it has worked so far so good just like the D-Tek. I will have to get back to you in 25 years if we want to compare it to the great H-10 I used to own that was always broken :whistle:

1 I want a leak detector that can find leaks without false alarms.

2 I want a leak detector that lasts...........

3 I will keep buying and trying till I retire or die, which ever comes 1st?

4 I will let you all know what has been a dud, even the Robinair/FP should it turn out that way.

5 I miss my Halide torch. :grin2:

[itsiceman]

I have found my ZX-1 will false alarm when bumped if dirty and and detects smmmall leaks better than both those I/R's
We may have a different interpretation of small leak but really sounds like you've had a 5hitty experience with tif which is completely believable.
All I'm saying is if the old tec of the ZX-1 has been better than I/R when all is right with the detectors and listed at .1 the new non I/R's that are even more sensitive should out perform the I/R's that are out to date on small leaks.
How old is your D-TEC?

I guess you had a better experience with your ZX-1? Mine could not find large leaks in R-409, 22, etc.

Our D-Tek is 2 years old, the first one had problems and the factory shipped us out a new one July 2009. My other tech is the primary user of the D-Tek. We also have a couple of the cheaper Tek Mates, and they have been OK for the money we spent on them. The Robinair is my newest experimental leak detector of the many I have owned. :whistle:

[itsiceman]

I believe affordable I/R suitable for field use has been tapped with the current sensitivity.
I/R can be to sensitive to other gasses in air that you are not trying to detect like pockets of different concentration of co2.
I don't believe I/R is going anywhere from here but there is still room for improvement for other types of sensors and the way the operate.
The ZX-1 was a big leap in that direction.

I have never tried any other IR detector other than the FP for any length of time but I am very happy with it's performance over my last tech mate for the smaller leaks.

With that said I will add that IMHO no matter which device you use it should only be used as a preliminary first run for the obvious leaks. I still rely on the old dauber and spray fluorescent bubble liquid and if that fails a last resort injection of dye. But that's just my :.02: for what it's worth.

[EugeneTheJeep]

Maybe I should stick the ZX-1 back in the truck for that phantom 410A leak, in the mean time it can piss me off if I bump it lightly and get its false alarms, and the board might screw up and I will have to pull the battery to shut it down.

[itsiceman]

I would have liked to try the zx but they don't make that anymore and usually newer stuff is less quality. Plus tif's name is not great IMO

From all the recent complaints around there must be a quality control issue.
You hear guys love it of hate it.
I will most likely not replace my ZX-1 with another or the new ZX because of what guys are saying :(
If I get one of the others I'll let ya know.

So far so good, but we don't do alot of 410A yet, mostly refrigeration leaks.

Is your h-10 as sesnsative with 410a as it is with R-22? Thanks

[RussellHarju]

Is your h-10 as sesnsative with 410a as it is with R-22? Thanks

I believe the H-10 has a 410a specific sensor. If you want one leak detector for all refrigerants you should use one with an infrared sensor.

[darctangent]

I believe the H-10 has a 410a specific sensor. If you want one leak detector for all refrigerants you should use one with an infrared sensor.

My H-10PM is capable with both HCFC's and HFC's. it's a matter of adjusting it properly. Not a big deal. I'm far less concerned about the sensor technology than I am the reliability, repeatability, sensitivity and false positives of a detector. I have a top shelf Infared, but that's where it stays- on the shelf. H-10 is my first line of detection. It takes me to leaks like a strong magnet. I can't tell you how much money I've raked it because of that thing.

[HAP2]

Based on feedback and performance reviews, I ordered the Fieldpiece SRL2K7 on Monday. Should be here today. The infrared sensor has a longer service (10yrs) life and should be good for any refrigerant type. We'll see...

Check out this video on how to use the SRL2K7 because it's just a little different than your typical heated diode. And it does detect all refrigerants on an equal level because of the infrared sensor.

Let me jump in Russell.

I'd love to have one and at let's say at 20-25 I think it would sell very well, although I could see an attempt to price them at twice that. I guess in the end I would be happy to buy one at 35-40

It should come with a small case to keep it from getting crap in it. I'm assuming it's a simple device except for the challenge of quality control on the hole size/leak rate.

The problem is they are more like $100. Maybe more. But considering a leak standard that has refrigerant in it can be $1000, this is still a pretty good deal. But are techs willing to spend $100 just to make sure their leak detector works, I am not sure of yet.

Wow. I guess I'm showing my ignorance!

I'm wondering why the cost is as high as that. perhaps I'm not understanding the complexity of the device or manufacturing cost? seems high for what it is, but I know better than to debate the issue with you, I will only say that bacharach produces that little test vial with refrigerant in it for far far less.

I guess I could see going $60. past that i don't think it's viable in this market, IMO. BTW, it's not portable, but I replaced a evap with multiple small leaks. now that I've identified all of them I use it for experimenting with different leak tests.

To be honest I don't know why the high price myself. It could be simple as the alternative is hundreds vs. only one hundred for theirs. Or it may be difficult to reproduce something with such strict tolerances. The little vial you are talking about doesn't have a standard leak rate so it can be produced much cheaper. Either way we are looking into to it because you know as well as I do it would be a very useful gadget.

Yes, who knows. I'm sure you'll sort it out.

I wanted to mention, I think it's great, and really smart business move that FP has a presence here. Good for you, good for contractors. Keep asking questions, looking for needs in product lines. I think you guys have enormous potential for growth. You could split product lines and develop some novel, innovative tools for HVAC.

[MechAcc]

Thanks Russ. It is a pretty neat tool. I imagine that when they test the flow rate they may have some failures due to the small rate involved. I just like being able to test the sniffer with any refrigerant.

[RussellHarju]

[ault51]

Thanks Russ. It is a pretty neat tool. I imagine that when they test the flow rate they may have some failures due to the small rate involved. I just like being able to test the sniffer with any refrigerant.

Ok...Couple/Few questions...

Exactly how would people use this? Do you want to test to make sure your sniffer is working before you go out on a job looking for a leak or something else? How often would you do this? Would this have any other use for technicians?

If you want to use this device to test your sniffer, how are you performing this function now without this device?

Would it be worth $75?, $100?, $150?, $200? to be able to perform this function? (just trying to understand what the cut points are)

What if you just had one that stayed at the shop for everyone to use when they wanted to?

[MechAcc]

What's that function worth to you?

Have to weigh the cost of one LS-4 vs buying a reference leak vial annually. Which depending upon type may run $ 35 to $ 50The LS-4 may pay for itself in 3,4,or 5 years.

As said mine was a present so I don't have the dollar (British pound) cost of the LS-4. I may be too low in this estimate but depending on manufacturing costs $ 100 to $140 for such a tool would not be out of line.

If this item costs more than that I would throw in added benefit of calibrating sniffer with the system refrigerant as an added plus because then my time is not being wasted trying to find a leak with a sniffer that will not detect low levels of a refrigerant. Might go to $ 175

[MechAcc]

Good points Ault. Many use up the reference vial that may have come with their sniffer and never replaced it.

Some detectors never came with a leak reference and the technician purchasing the detector are unaware of a leak reference.

So many are not testing their sniffers or they are cracking the valve on a refrigerant cylinder an do gross leak test on it. Then cannot find small leaks with afterwards. By testing against a referenced leak they would find that they need to clean or replace tip filters or the sensor is deteriorating in strength. Time is money.

Primary for me would be to pre test the leak detector against the refrigerant I'm testing for, in the field. there are many times I wonder about the current condition of the leak detector and this would verify it. The other thing I worry about are false positives, but that's not on topic.

If you want to use this device to test your sniffer, how are you performing this function now without this device?
in the field, I use whatever's handy- refrigerant ports, virgin jugs, recovery tanks, manifold gauges. You can usually find something that's giving off a little bit, but you never know how large or small it is, unless it's spewing out refrigerant, in which case it makes the test almost completely pointless. I want a SMALL leak, not a big one.
Would it be worth $75?, $100?, $150?, $200? to be able to perform this function? (just trying to understand what the cut points are)
As I said before, $60 seems to be the top for me, others will vary. I think a big part of it is in the confidence you get with your instrument. There's always another way to test, see my post above on my old evap coil.

What if you just had one that stayed at the shop for everyone to use when they wanted to?
Not for me I don't think. I sort of makes sense for bigger shops though.

Let me jump in Russell.

I'd love to have one and at let's say at 20-25 I think it would sell very well, although I could see an attempt to price them at twice that. I guess in the end I would be happy to buy one at 35-40

It should come with a small case to keep it from getting crap in it. I'm assuming it's a simple device except for the challenge of quality control on the hole size/leak rate.

:.02:

The one given to me did come in a small storage container.

[Pascone10]

Russell I would buy one. Personally I would like to see it come in around $50..

But as others said I have no idea about manufacturing costs..

Thanks to all your responses. We will continue to look into it.

[EugeneTheJeep]

What is this magic leak rate device? Will we be able to screw it on to our own cylinders? I would think a 1/4" fitting with some sintered metal in it, could be restricted to a miniscule leak for testing our detectors?

Yes. It screws onto a refrigerant cylinder. Has 1/4" flare connection. See video that I posted on the one I tested.

The ZX-1 took a long time and alot of persistence, I would have never found a real leak with the ZX-1, throw that one in the trash.

The FP was quick and passed the test.

The D-Tek was quick and passed the test.

Sensit was quick and passed the test.

Inficon was slow but passed the test.

YJ throw that one in the trash.

Tek-mate throw that one in the trash.

H-10 was quick and passed the test.

Good test, now we know what detectors work and which ones don't of the few that were tested.
:cheers:

[itsiceman]

Obviously my detectors don't react like that vs each other.
Guess there's only one way to find out if something is wrong with your ZX-1 or I need to replace my SRL2 for a second time. Can I try my detectors with your reference some time Mech?

[nratom45-70]

Thanks to all your responses. We will continue to look into it.

I'd buy one at that price ($50.00).

[slahac]

I believe the H-10 has a 410a specific sensor. If you want one leak detector for all refrigerants you should use one with an infrared sensor.

The H-10 has specs for leakrate detection for R-12 and 134-A and the detection rate is much better for R-12 than 134-A.

http://www.synmactech.com/Products/Productpage/H10G.php

Does it seem to reason that 410-A would be detected with less sensitivity than either R-12 or 134-A, or R-22? There has to be a million guys out there with the H-10, has anyone noticed? Thanks

[itsiceman]

I would think with a fixed reference leak like the one tank will leak more with 410 vs 134 so not really good for comparing like that.
Have you tried any of your ultrasonic detectors on the leak reference Mech?

[MechAcc]

The leak rate is more of a seep. Ultrasonics don't seem to work that well in that range even my Accutrak.

basically, when the leak is large enough to have an effect on the system and somebody has figured out that a leak is likely, the H-10 does just fine.

Ask yourself this- how many systems with a leak rate of .1 oz/year would you actually be trying to find a leak on anyway? Don't get me wrong, but lets get realistic about what we normally use these tools for.

I think it's time for a new sensor on my H-10, and I'm happy to spend the money because of just how damn good it does it's job.

[energy star]

Man I can't make up my mind at all. Now I feel as if the FP or H-10 is the ticket. I gotta get one soon, have a leak in a package unit I can't find.

I've said my opinion, but I think either one would do fine!

You really can't be with one in the summertime.

My update:

I called Bacharach. I told them I was in the market for a leak detector. I'm not concerned with the price at this point. I asked him what was the best leak detector your company makes. The Informant 2 was his reply. I asked him what about the H-10PM? He said it's a good detector, but I feel the informant is better. He told me that GE made the H-10, they sold out to Yokogawa then were bought by Bacharach. They have no IR detectors unless you wanna spend 9k. Just keeping my findings on this topic alive, going to call Fieldpiece now.

[Pascone10]

So you want to go the infrared route?

I've talked to them too, and I can tell you they are a good bunch of guys, no doubt about it. The guy I talked to did have a belief that IR is they way to go, but let me say this- the most sensitive is not always the best. it's not the only thing that matters. being able to trust the results you get matters too. absence of false positives matter too. flexibility of tuning matters. I can crank the sensitivity of the H-10PM sky high, or I can drop it down, or anywhere in between. when you crank up the sensitivity on the H-10, you shorten sensor life so I wouldn't do it on a lark, but when you need to get the job done, it's there for you.

Do what you wish, there's more than on good leak detector out there. I'm just telling you when guys it a lab, or any office just don't get, and why the H-10 is as cool as it is after all this time. It's the equivalent of a 90's ford pickup. sure there are fancier models out there now with better creature comforts, cup holders and crap like that, but none of that matters when it comes time to get the job done.

That damn thing just plain works, and works well. When is the last time somebody came on here and said that the H-10 sucks balls? hmmmm?? If they took care of it and knew how to use it it doesn't happen.

What ever you do, let us know after a couple of years what you think.


PS- whatever one you get, odds are when CO2 comes out you'll be getting another one anyway.

Stop being paralyzed and get back to work!!!!

[HAP2]

Real happy to report that the SRL2 picks up the "Envirosafe" type refrigerants found in the 609 world really well too.
One thing I found odd is the manual says not to store the unit with a fully charged battery...??

[Rcb2875]

The are 4 sensitivity settings from low to turbo on the SRL2. One case in which I had the unit on high I thought I was getting a false positive because while I was checking the braze at a know leaking unit at the service valves I would get a short hit as I pulled the meter away. It did this about 4 times. I thought maybe it was pools of gas coming from the wall since the hole wasn't sealed so I tried there. I got two more hits as I pulled the meter away there as well.

Turns out that there was a coupling mid way between the wall and the condenser I didn't notice since it was below the suction line. As soon as I placed the unit at the coupling it would hit. I decided it was a good chance to play with the settings. adjusting from high to low stopped the mid air detecting and only hit when I put the tip at the coupling. Not sure the leak rate but was not very bad nor very small. Would leak probably a pound a year since I had last serviced that unit.

O.K. darctangent, I'll get a new sensor also, it's been years since I replaced it. No one has really answered my question about my H-10 lack of sensitivity with 410-A, so I'll get the new sensor and report back. Thanks

Get the Bacharach Tune up kit P/N 3015-0781 comes with a new sensor, 100 filters, 3 replacement balls, 3 rubber tips, and a reference leak vial. About a $130 on one on line store far far less than if you ordered each item separately. Be careful if ordering on line some are listing the 3015-0784 Maintenance kit as a 0781. The 0784 does not come with a sensor.

spray some good bubble solution on the leak source and then take a listen. :grin2:

Me too.

I got my own "reference leak" , I'll start calling it my "reference coil" - one evap coil, one "medium" leak and four teeny ones.

It's not as small as yours, I can't fit it in my pocket! But hey, I got it for free!


I was talking about putting the bubble solution on the leak source... in this case that little cap. since it's under continuous pressure you shouldn't foul it, you'll just have to clean it off before you separate it from the bottle.


just because it's been brought up, do you have any idea how that thing works? is it a teeny hole in a cap? is there some diaphragm setup? what makes that thing tick?

[Pascone10]

Eugene the jeep: hows that detector holding up?

I'm really considering IR detection b/c its different then my H10. I really should have bought the PM.. Oh well..

Ill be honest tho I am really doubting buying the Fieldpiece ( that I wanted originally). I keep hearing quality issues with the FP Stuff. I mean where was the R and D with them valves on the SMAN? I know Russell will make it right but I am honestly worried I am buying a lower quality product if I go the FP route. I just hear of too many problems. It also doesn't help that I don't like their meters...

SO now Im thinking Dtek select.. It is the good ol faithful. Just wish the battery was better. Plus united stocks them...

[thes]

i have a question, does any one think a electronic leak detecter works on r-22 the same as finding a 410a leak ,

O.K, here are the official results of my Mythbusters style testing with a new sensor for my H-10 leak detector. All testing was on the medium leak setting.

Sniffed 4-10 hoses. No response until the probe was inserted into the hose. Then a moderate response was noted.

Sniffed R-22 hoses. Moderate response around manifold connections, screaming response when probe inserted into hose.

My friend (not me) allowed an approx. 1 second blast of 4-10 to escape into the back of his (not my) enclosed cargo trailer. No confirmed response inside the trailer until probe was inserted into nozzle of the 4-10 canister, then a moderate response was noted.

My friend (not me) allowed an approx. 1 second blast of R-22 to escape into the back of his (not my) enclosed cargo trailer. The probe started screaming out side the trailer door from drift before we ever even got close to the inside.

This is a funky test, and many may find fault with it, but in my book, where there is smoke there is fire. I say it's confirmed, the H-10, a standard in my arsenal for many years, does NOT pick up 4-10 nearly as well as it picks up R-22.

i some of these electronic lek detecters i was wondering the same thing, if they are as sensitive with 410A as they are with R-22

i'm wondering if the apoe OIL HAS ANY THING TO DO WITH IT. I STILL THINK THERE IS A LEARNING CUVE WITH THIS 410a REFRIGERANT AS COMPARED TO R-22!:angel:

[joemach]

Love the h10g and detec select don't like the charging time on the detec

I have no problem with the battery on the D-Tech Select.

The great thing about it is that you get a house charger and one you can charge in your truck as you drive.

I charge mine once a month at home and never needed to use a truck charger.

I would contact Inficon to find out what the problem is and get it resolved.

[nyc_badboy]

i personally own the FP srl2k7 i have done over 100 leak service calls with it so far it didnt find the leak only once on r22 split unit only becasue it was traveling through the insulation on the other side . once i removed that no problem it pinpoited it withing 4 min. so far it hasnt dissapointed me even though in some cases there was oil in places from the previous tech it settles down and keeps searching. one of my fav tool in the van...my 2 cents

Well my zx-1 is dying I have had it repaired once already, I was using it Satruday and it was reading then not reading a leak, it won't power down anymore I have to pull the battery to turn it off. It worked great for couple years, so now I am in the market for a new one been thinking of a fieldpiece one but not sure to go IR or not.

[itsiceman]

Here is my ZX-1 with MechAcc's R-134a reference leak hooked up to a R-410a jug like he had shown is his video.
After seeing this I believe something is wrong with his ZX-1 detector.

Before this I tested outside in a light breeze for a more realistic test
"My" ZX-1 did the best at detecting the R-410a leak IMO with "My" SRL2 coming in second and no leak detected with "My" SRL8.
I will be changing filters on the Fieldpiece units tomorrow to see if any changes are observed.

FWIW Indoors the SRL8 did hit slightly on this reference with some persistence.

Might be connection speed and not getting enough buffer Mech.

It's basically a screaming ZX-1 Detector on that reference leak running R-410a .... even got a wif with the tif in low mode :whistle:

If you are still having trouble maybe I could just e-mail you the video file.

Do you have a H10 or an Inficonn leak reference bottle that you can compare the LZ-4 to?

[itsiceman]

Nope I never got a H10
I was good with a Halide and then went to D-Tec when they were new

[itsiceman]

I got around to testing R-22 with my detectors in the back of the garage with the door open and jug on the floor no breeze @ 70˚F

With the reference leak my SRL2 and SRL8 did not pick up anything and my ZX-1 was screaming again.

I changed the clean filters on the Fieldpiece units with new clean filters and got the same result -0- leak detected with either Fieldpiece unit.

I have some R-134A setting up now and will try the R-410A again.

At least from the videos it appears something is wrong with both SRL2 and SRL8 unless being outside makes that much of a difference compared to inside where you did it Mech.

At least now I can see why I'm so frustrated with these Fieldpiece detectors but I still not sure if if there is anything wrong with them or not.

[itsiceman]

Now I can see it. Thanks. How did you like testing the LS-4?

It is a simple device that is only calibrated for one pressure.
When connected to something like R-410A or a hot or cold drum of R-XXX it is merely a reference leak but still useful.


Video looks good....but, did you shoot it in a mirror???
Yep smoke and mirrors
Thats the only way I could find a small R-410A leak with a heated sensor :p

[EODVET]

Okay, so I've spent the rest of the summer comparing the sensitivity of this tool between R-22 and R-410a and there is a difference. It picks up the R-22 from quite a ways away (3-5ft). You have to move over the surfaces of the piping system (within 6in.) to detect R-410a but it picks it up right away. In terms of R-22 it picks up concealed leaks (under the insulation and other things) very well. You have to remove the insulation for 410a detection. This is by far the best meter I have ever owned.

There are 2 quirks that I found with this unit however, if you are in wind or are sniffing near a running fan, you will get false readings.

Also, the sensitivity scale is much more balanced when detecting R-22. with 410, it's either screaming or it just barely ticks. After getting used to it, I found that you just stay near the tick and get really close and move the tip slowly. You will hit gold pretty quickly.

99% of the leaks I found this summer were due to poor brazing... Which also means that the systems were not evacuated properly to begin with. Shame, shame....

Best find of the summer was when I was called out to a new install to find a leak (they couldn't keep the unit running correctly either) and I knew almost immediately that there was a kink somewhere. So, I went to the last place anyone would want to look (the attic) and found a kink under the insulation. The kink has a small tear in the corner. Recovered, repaired, evacuated, recharged and the homeowners were happy little clams.

I hope I have helped a little and don't come off as the idiot that I was portrayed to be a few pages back.

I think the guy was just mad that I don't like Fieldpile.. Whatev

[r-290]

A lot of posts in this thread.

Ok my problem. They re stucco the building and suspect a staple hit a line inside the wall. Need a way to find the leak area so I only cut one hole in the wall to fix it. Will cut the sheet rock from the inside vs the brand new stucco. The line run's from the attic down 2 stories to the ground.

I'm thinking a stereoscope. Not sure if an ultra sonic would work inside a wall.

[hvacrmedic]

You should have started a new thread in a relevant forum like Pro's Forum: Residential.

[r-290]

OK never mind I figure it out like everything else :cheers:

FWIW I ordered a stethoscope to see if that will help. Worst case remove 16'x16" of sheet rock.

[coolperfect]

The few times that happened to me,I had to run a new line or cut the line at top and bottom,pull it out,fix it and put it back!

[MechAcc]

The ultrasonic will work better than a stethescope. It amplifys the sound.

[r-290]

The ultrasonic will work better than a stethescope. It amplifys the sound.

Thanks, one of the issues I have is the place is right next to the freeway.
So it makes it harder to hear. For $20 can't go to wrong with the scope.

I looked at the ultrasonics which is why I posted in this thread. Not sure which one is the "one" to get. I hate buying tools twice, when I should have done better research. The Fieldpiece is an IR, I don't think that will work through sheet rock.


Anyone own the Thermal Engineering ultrasonic meter?

[tostaos]

I own one and would buy it again. But it's only one tool to find leaks, sometimes it's better, sometimes not compared to my other leak detector.

[R&J-R]

The H10g/pm are my go to detectors. I've had the pleasure of using the Zx-1 and YJ accuprobe. They both worked well in the first 3 months but started dropping off in performance until failure. Kinda scar'd now from those type of plastic bodied sniffers. I rarely work with 410a but the h10 family has yet to let me down on a 410a leak. False hits on h10's are close to none. It's been observed when walking into a bakery chill with moving product and rising dough, it will quickly false alarm and then stabilize.

The FP IR looks to be something I'd like to invest in. Though it seems on a couple videos that the sensor is almost touching the reference leaks. Do you normally have to be close with the IR? Can you stand a couple feet from a coil with a slow swinging motion and still get the general area where the leak exist? In the videos it seems that the FP IR refrigerant detector have an air pump which depends on sucking up praticulates. When I think of IR, Flir or Fluke imagers come to mind. Are there lenses inside the FP that detect IR after particulates hit the filter? Really interesting stuff.
