Thermocouple Calibrators (IT52.50)

PORTABLE THERMOCOUPLE CALIBRATOR, IT52.50 incorporates in a single instrument a high precision but low drift mV source, Automatic Cold Junction Compensator and an accurate 3½ digit LCD, mV read out. IT52.50 simulates as well as measures Thermocouple mVs accurately and is used for measuring the Thermocouple outputs and calibrating instruments like Transmitters, Indicators, Controllers, and Recorders etc. having Thermocouple input.

Since Automatic Cold Junction Compensation (Ref. Temp. 0°C) is built-in, IT52.50 takes care of the ambient/room temperature variation while measurement and during simulation.

0-20 mV & 0-200 mV DC ranges, with resolution of 10 µV & 100 µV respectively, are selected by Function-cum-Range Selector in both simulate & measure modes. J, K, R & S Thermocouple or mV Sensors are selected by Sensor Selector, enabling measurement & simulation of most Thermocouples used commonly in addition to mV for any other sensor. Precise & stepless adjustment of mVs is done by a ten turn “mV adjust Potentiometer” and read on digital display.
