Process Calibrators


Extech Instruments announces the introduction of the new PRC line of process calibrators to test transmitters, transducers, indicators, sensors and other industrial process components. The four new meters -- PRC10, 15, 20 and 30 -- offer plant and electrical technicians simplified controls to monitor and calibrate process systems easily for optimized operation. Extech PRC calibrators feature an ergonomic, compact design with a durable housing made for long service life. Large, illuminated dot-matrix dual displays ensure easy viewing of both source readings and measured values like loop current, temperature, voltage, etc. Up to five configurations can be programmed by the user for expedited testing. Available AC power makes it easy to perform continuous or extended testing in the field or on the bench. 

The PRC Series includes the following models: 

  • PRC10 Current Calibrator: Source: 0-24mA; measure 0-50mA; 24VDC loop power
  • PRC15 Current & Voltage Calibrator:  Source: 0-24mA and 0-20V; measure 0-50mA and 0-20V PRC20
  • Thermocouple Calibrator: Source and measure 8 thermocouple types: C, E, J, K, N, R, S and T; -10-60mV
  • PRC30 Multifunction Process Calibrator:  all features of PRC10, 15, and 20 combined 
The PRC10, PRC15, PRC20 and PRC30 each come complete with a hard carrying case, universal AC adaptor, test leads, alligator clips and/or thermocouple calibration cables, plus six 1.5V AA batteries.
