Calibrators

Digital Calibration Unit
Model : ALC-02 mV only / ALC 04 mV and ohms / Model : ALC-05 mV and mA

(Configuration and labeling will change depending on Model number. )

The Artech Thermocouple Calibration Units are simple, sturdy instruments which eliminate the need for cumbersome calibration potentiometers. The instruments are light weight & portable. There are two modes of operation : a) Measure - for measuring millivolts, ohms, milliamps output of sensors and b) Source - to generate mV, ohms, mA which can be used for checking instruments. The readings are clearly indicated with a resolution of 0.01 mV/ohms/mA.
