Fluke 2176A thermocouple thermometer
(OP)
Hello. I have a Fluke 2176A thermometer that is calibrated to type T thermocouples. I have K thermocouples. The unit is supposedly also good with K thermocouples, but I do not see how to let it know there are K thermocouples attached. Does anyone know about this thermometer? I thought I'd ask before tearing the thing apart to try to tell. It seems if I put a thermocouple different than a T-type, I will get an inaccurate reading. Right?
Thanks!
Thanks!





RE: Fluke 2176A thermocouple thermometer
The discrepancies you've detected when turning from T-type to K-type are in the nature of the thermocouple itself. Thermocouples type K and T have a different range of applicability. For type K (-210 °C to 1370 °C) while for type T (-210 °C to 400 °C). Their accuracy is different as well. The reference standard is IEC 584-2. If you have not access to this standard take a glance at the link below

At 350°C, the reading error would be about 96°C
Closer to room temperature, the differences are less than the inherent uncertainties in the measurement itself.

This is my plan: use the K-type thermocouples with the T-type thermometer. The reading will be a temperature resulting from a supplied voltage due to the temperature the thermocouple "sees". Using the cool converter supplied by IRstuff or charts that can be found online, like here:

(See thermocouple reference data section)I can convert the read temperature to a voltage on the T-chart. I then go to the K-chart and use the voltage to find what the real temperature is.
Let me know if you guys think I'm crazy and I'm missing something!
Thanks!
