Diagnostic Thermocouple & mA Calibrator PIE 422Plus

Brand: Practical Instrument Electronics, Inc

Calibrate all your thermocouple instruments AND your milliamp loops with the PIE 422Plus. It has all the functions of a 14 type thermocouple calibrator and can source 0 to 24 milliamps or simulate a two wire transmitter like a milliamp calibrator. 

You may also perform stand alone calibrations of two wire transmitters by simultaneously supplying the thermocouple input signal while supplying the 24 volts to power up the transmitter and monitoring the milliamp output signal. 

Powers HART™ transmitters with built-in 250 ohm resistor simplifying hookups with HART communicators.
