    Digicool Temperature Accuracy

    My digicool clamps are about 10 degrees off from my Fluke 52II WITH 80pk clamp. What’s the most accurate way to see which one is wrong?

    Put both probes in a glass of water with ice and see which hit 32F.

    might want to be sure both batteries are new or good at least.

    So which sensor was wrong? My money is on the Fluke K-type.

    Haven’t checked yet. Been too busy. I’m just banking on the digicool being correct for now. They are closer on air conditioning temp range. The huge discrepancy was when checking superheat on freezer with suction line temp below 0

    digicool uses 10k thermistors so they are more accurate. I’ve never had a thermistor read “off”, they either read correctly for their Ohm/temp curve or they read open.

    K type thermocouples are notorious for being “off” by several degrees. Even a $175 fluke one.
