Universal Desktop Calibrator

IT 53 Series of digital test sets and calibrators are portable instruments suitable for measurement & calibration in instrumentation departments, scientific laboratories, research institutions & for field applications. Three models are available to cater to various demands and measurement requirements.

While IT53.01 and IT53.02 are 3½ digit Calibrators, 1T'53.03 is a 4½ digit Calibrator. All the models have reference junction compensation, built in for J, K, R & S thermocouple output measurement and are capable of simulation of thermocouple output for calibration and testing of temperature instruments. IT53.01 and IT53.03 are also provided with measurement and simulation of Pt 100 DIN RTD.

For measurement & simulation of DC current, IT 53.02 & IT 53.03 are ideally suitable. IT53.
