Automated Thermocouple Calibrator - 14 T/C Types


With the PIECAL 422 you can check & calibrate all your thermocouple instruments and measure thermocouple sensors. Plug in any thermocouple via a miniature thermocouple jack.

Carry it without worry - it comes protected with a rubber boot and rugged, low profile switch. The PIECAL 422 is easy to operate, even in the dark areas of the plant with the backlit display.

Stop carrying around a millivolt source and thermocouple tables. The PIECAL 422 works with the thermocouples you use, including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and
P (Platinel II). You can easily set any value quickly to within 0.1° with the adjustable digital potentiometer “DIAL”, store any three temperatures for instant recall with the EZ-CHECK™ switch, or even calibrate from -13.000 to +80.000 mV.
