Tool to measure superheat, subcooling?

[EEAllen]

What tools do you guys use, specifically to measure the line temperature? I've seen those tool that can measure the pressure at the valve, and the clamp tool to measure the line temperature, but was that worth the investment? I am fine with just calculating it manually, but what temperature measurement device do you guys use?

Digicool ak900 with scissor clamps or cooper atkins blue box or fieldpiece meter with atc1 clamp thermocouple.

he asked about a temp tester not a digital gauge.

Um, read the title of the thread.
The ak900 does this.

he asked about a temp tester not a digital gauge.

Incorrect, he also stated that he's seen those things that measure the valve pressure and measure the line temp and asked if it was worth the investment because he's ok with doing the math now.

I don't know of any temp testers that measure pressure, line temps, and do math that aren't digital gauges.... Like the DC AK900's : P

^I use one of those with a cooper red box, and analog gauges. Or I use my Digicool ak900.

He asked specifically how we measure superheat and subcooling.


I use a DC 1200 or an AK900 to measure superheat or subcooling.

Sounds like hes asking for a temp tester to me.

But either way....I would use my Testo 570 with sensors.

If any of you were at all adept at listening...truly listening; you would realize he was really wondering how to achieve inner peace - along with 8-10* subcooling.

Jeesh!

JB and FP make decent SH/SC instrument .

I thought it was 12* to 15*? Whose specs you quoting?

Carrier residential. I do see a few data plates with 11*...

I've seen some tranes go down to 9*

Did JB start making them again? The one they used to make has been discontinued over 1 1/2 years.

Love my Testo 570, and YES it is worth it.

[Grayline]

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!
