Vartech Calibrators — mV, mA, Temperature & Process
As the authorised dealer for Vartech in India, CIE Instruments supplies three Vartech process calibrators: the V 7220 R temperature calibrator (DCV, T/C, RTD source & measure), the V 7221 B loop calibrator (0–30 mA source, ±35 mA/35 V measure, sawtooth/triangle wave) and the MS 7221 V/mA calibrator (0–24 mA / 0–10 V with 24 V loop supply and 0.015% mA accuracy).

About Vartech Calibrators — mV, mA, Temperature & Process
Process calibrators are indispensable tools for instrument engineers and calibration technicians working on industrial process control loops, temperature transmitters and field instruments. The Vartech calibrator range covers three essential applications: temperature/RTD/T/C calibration (V 7220 R), 4–20 mA loop calibration with waveform output (V 7221 B) and precision mA/voltage source-and-measure (MS 7221).
The MS 7221 stands out for its very high loop current accuracy of 0.015% with 1 µA resolution and a built-in 24 V loop supply — enabling single-instrument calibration of 2-wire transmitters without a separate power source. The V 7221 B's sawtooth and triangle wave outputs are particularly useful for valve stroke testing and control loop checking.
