Practical Instrument Electronics offers the PIECAL 521B 14 T/C Types Plus mV Source for checkout and calibration of a range of thermocouple instruments for an expanse of applications.
The PIECAL 521B replicates a standard thermocouple curve over the entire industrial temperature range delivering precise temperature for inputs to an array of instruments like controllers, computer systems, recorders, alarms, transmitters and data acquisition. The miniature thermocouple connector on the top end allows for quick connections.
Topping other thermocouple calibrators, the PIECAL 521B offers the most in performance and functions.
