The PIECAL 521B Thermocouple Source simulates a standard thermocouple curve over the entire industrial temperature range. The PIECAL 521B provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition and computer systems. 

The PIECAL 521B has a miniature thermocouple connector on the top end for fast connections. It offers high performance and functions by exceeding the accuracy and functions of many of the higher priced thermocouple calibrators.

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