Process Calibrator Reccomendations?

<< < (4/5) > >>

TimFox:
You can invert the measurement I suggested to check the calibration on your reasonably-priced calibrator against a physical ice-point and a calibrated voltmeter.

J-R:
Extech PRC30 seems to be an interesting budget option, $850 with NIST certificate.  They are in stock.

TimFox:
Note that for my J example at 1000o C, the thermal emf has a slope of 0.06 mV/K, or 0.1% of value per degree.
This is useful to determine what voltmeter accuracy is required either for calibrating the thermocouple meter, or the inverse circuit for checking the calibration of the thermocouple-simulating calibrator.

There are also Omega calibrators: https://www.omega.com/en-us/calibration/temperature-calibrators/c/handheld-calibrators

I own the simplest CL3515R and it's pretty good. They still sell it and offer support and recalibration.
But there are certainly better / newer models.

Upd: they have multifunction calibrators as well https://www.omega.com/en-us/calibration/c/multifunction-calibration but I have no experience with them.
