Tool to measure superheat, subcooling?

I used The testo 570 side by side with my Field piece ssx34 one touch between SH& Sc and saw a big difference in speed and the testo was always 5-7 deg off.
But I do Love my 570 for everything else!

Are you saying the 570 is less accurate than Fieldpiece SSX34?

I use Fluke 54 II B and it is good..

I use a Fluke 116 meter with fluke pipe clamp and do the SC/SH calculations manually. I like the pipe clamps better than the velcro wrap sensor for smaller diameter pipes.

More like your FP is off than your 570. How long you had the 570 and how often do you calibrate your FP temp clamp?

Is the fieldpiece ssx a good investment?I have been thinking about buying one but I have not ever talked to anyone that has one.

It's ok, but you would be better off with an SMAN 3 or an SMAN 4.

I have used the 116 too but I hate having to use the adapter with the pipe clamp.I have had 2 to pull apart when I went to take the clamp out of my meter.I do try to take care of my equipment.Have you ever had this happen?

I have an ssx34 by fieldpiece. It was 250 when I purchased it 2 years ago. Now was it worth it. Still not sure. There's nothing it does that I wasent doing with my gagues and a thermometer and tape. It does make things a bit quicker and some what more convenient but the price tag is a little high for this minimal convenience. Put it this way, the batteries died last month and I haven't changed them.

have a care using a fluke 116 for temperature. even fluke admidts its only good for general measurements.

the internal reference thermocouple is buired in what fluke cals a thermo-isolation block to stabilize the readings against the meter body temp changing. but that same thermo-isolation block greatly slows the temp stabilazation when you need it. it also has no emf shielding .

the reality is the meter body, the thermocouple and that stupid adaptor all need to be at the exact same temperature or else the reading is inaccurate.

you really need a meter that is designed as a thermometer such as a fluke 52/54 series or a cooper that uses thermisters for an even more accurat albeit slower response. the top 3 DRSA manufactures employ decent thermometer technology

I don't see the purpose of a stand alone SH/SC calculator. I'd save the money and do it manually or throw a little extra with it and get a drsa that will do that and more.

I had one when I first started and it was very helpful. Ended up giving mine away to one of the new guys now that I have the formula, I don't really need it anymore.

I use the thermocouple that came with my uei meter and a $1 clamp from Harbor Fright.

I think there is an app for that.

[lexscripta]

A One dollar clamp? You must mean one of those plastic clamps to hold the thermister lol.

I have UEI, and they work great. I did buy 2 fluke thermister clamps on ebay though. Works great when working on 2 evaps at the same time

I believe You might be on to something.With the bead you're getting a pin point reading and the clamp would insulate it.I have been thinking about this ever sense I read it and I am definitely going to try it.Some people are always thinking! What type of clamp do you use?A bar type or squeeze type?
