h10G leak detector

[thecarpenter]

Hoping more people in another thread would advise about their favorite electronic leak detectors, but....., am looking at a hardly used Bacharach H10G, Mars 25303 on Ebay. have H10's changed much or is an H10G an H10G , is it worth looking at or if I am going to drop a bundle, should I go for the H10 PM? Was thinking the Ebay H10G would go for a few hundred, but don't know if there are parts that wear out and need replacing or if the newer ones are more efficient. I don't mind paying for something that works, not a brand name.
Thanks
Greg

The H10 (with whatever suffix) Is still the best leak detector available. I got a new one last year and it's still the same basic unit with some minor improvements. There's also a battery powered model available.

H10 G is what I use.

I also use the H10G , i love it will never waste my money on anything less! be careful buying them used. there very sensitive and easy to screw up. I went to help one of our guys fine a leak a while back, and he took it apon himself to see if it was working and stuck it straaight in a stream of refigerant. saturated the sensor in it (new sensor $103) thats the last time he will ever look at much less touch my sniffer. If your get one keep it away from careless hands.

BS.

You won't ruin an H-10 sensor that way.

I've done it enough to know.

Water is a different story. I've unfortunately done a few doozey's with water and H-10's though, even being very careful. When you realize you've done it, it's too late. Time for a repair.

I always swore by my H-10's, until R-410 came along. Then I began to second-guess them. We have had decent results with the TifZX on 410. It has been a while since I've done 'duelling leak detectors' on 410. Might have to give it a go again.

Ditto on water. Not good for pumps.


The h-10 works great on HFCS refrigerants. Far better than the Inficon, TIF and CPS models that I've tried.

As others have stated the H10G is by far the best. However be cautious of anything off the internet. Yesterday one of our dealers brought in a "new" H10 he just bought on e-bay and asked me to check it out for him. It was actually a H10 B which was what I used 30+ years ago. It would not sense anything and there are no longer parts to repair the B model. OUCH !
For checking R410 you can adjust the heat range for the sensor by turning the screw located on the back of the case ( without removing it ) full clockwise and then back it back about a 1/4 turn. For the very best results on hard to locate leaks recover the r410 and add a little r22 and nitrogen and then leak check. All detectors are not as sensitive or accurate with R410.

BS huh! I watched it happen, after the guy Saturated the sensor, i tried to get it around 2 clicks a second and it wouldnt even stay clicking, and it also wouldnt alert on the calibration bottle or r22, tried to calibrate it and didnt help.. put a new sensor and it works like a champ.

I've put an H-10 in some serious leak streams. Bigger than you could possibly encounter in a residential system and have NEVER seen anything like that happen.

I still don't buy it.

You aint gota buy it im telling you it happend. Hook your gauges up, take ur high side hose off your manifold and blow it into your sniffer, see if it dont it up. And it was on a 20 ton york. Anyway its all good man you got it.

ive poisoned a few sensors but not the h 10 we even dropped one into liquid r 22 in a cup { before the epa days{ & the next morning it was plugged in & still operating

The sensor will be damaged by a large intake for R134A or R12.
I have been using the H10s for over 20 years, been through 5 units and 12 or more sensors.
