Extech PRC20: Thermocouple Calibrator
Precision Multi-Thermocouple Source/Measure Calibrator
The PRC20 sources and measures eight thermocouple type devices (J, K, T, E, C, R, S and N) and provides precision output displayed as Centigrade/Fahrenheit or mV. It has five user adjustable calibration presets and a Type K temperature range of -58 to 2498 degrees F (-50 to 1370 degrees C). The PRC20 is suitable for Lab and field calibration, Engineering research and design, Manufacturing and test engineering, Temperature control process troubleshooting and HVAC applications. Comes with thermocouple calibration cable with subminiature connectors, standard calibration cable with subminiature connectors, 100V-240V AC universal adaptor with four plugs, six 1.5-volt AA batteries, hard case, and user manual.
