PIECAL 422 Automated Thermocouple Calibrator

Stop carrying around millivolt sources and thermocouple tables! By connecting the PIECAL 422 to a miniature thermocouple connector, you can measure and calibrate your probe directly in °C or °F. The PIECAL 422 is compatible with smart transmitters, PLCs, DCS and multichannel recorders.

PIECAL's 422 can help troubleshoot sensor connections and find broken wires or corroded connections. The 422 thermocouple calibrator is comparable to Altek's model 422.
