    Tool to measure superheat, subcooling?

    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?

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

    He asked specifically how we measure superheat and subcooling.


    I use a DC 1200 or an AK900 to measure superheat or 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?

    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?
