    The solution to "Giving up stem thermometers forever..."

    I had to make some compromises to get the differential thermometer I wanted.
    http://www.ueitest.com/sites/default...es/dt304-1.jpg
    My priorities were:

    1. Size
    2. Country of origin
    3. Ease of use
    4. Accuracy
    5. cost

    Final decision is the UEI DTM 304. Four K-type inputs.
    NIST Calibration Certificate.
    Self explanatory operation.
    Fits easily in one hand.
    Temp off set, back light, big screen and numeral.
    Made in Korea.
    Less than $175 shipped.

    UEi Oh Brother 5646. My dual input that won is the worst thermocouple thermometer I ever used. Very susceptible to EMI. Did you check on the UEi thermistor version or did you really want the 4 input that bad.

    I have a hatred for k-type thermocouple thermometers. To each his own though.

    I was expecting the UEI bias to arise. That was why my choice was an NIST certified accuracy.

    To be honest I must have missed the thermistor model you mention...I doubt I would have made a diff choice, however. I did make some compromises as I stated in the post.

    Thermocouples are faster reacting...this UEI is very fast.

    Is the NIST cert just for the programing? It says +/-2˚ between 64˚ and 82˚meter accuracy and doesn't include thermocouple error. Well at least it has the offset. Mine has no way to fake the reading.

    No bias 5646. I was going to buy that exact meter when it came out. The one I got to use ended that but I still use my DL389

    Bought an DT20A thermistor differential meter today too.
