Read & Source T/C Calibrator
8 Types Plus mV

The Practical Instrument Electronics (PIE) Model 522 is a complete source/read thermocouple calibrator providing direct temperature input to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The Model 522 is internally cold-junction compensated for accuracy in any operating environment.

The PIE Model 522 offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators. It is a low cost solution for checkout and calibration of all thermocouple instruments in the field, shop or control room.
