521B PIE 14 Type Thermocouple Calibrator

521B 14 T/C Types Plus mV Source:


The PIE 521B Thermocouple Source simulates standard thermocouple curves over the entire industrial temperature range. 521B provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The 521B has a miniature thermocouple connector on the top end for fast connections. The PIE 521B offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators.

The low cost PIE 521B is an “easy as PIE” to use thermocouple source for checkout and calibration of all thermocouple instruments in the field, shop or control room.
