About Calibrators — mV, mA, Temperature & Process
CIE Instruments supplies three Vartech process calibrators: the V 7220 R temperature calibrator (source & measure DCV, Resistance, T/C and RTD — 2W/3W/4W), the V 7221 B loop calibrator (source 0–30 mA DC with sawtooth/triangle wave, measure ±35 mA and ±35 V), and the MS 7221 V/mA calibrator (0–24 mA / 0–10 V with 24 V loop supply and 0.015% mA accuracy).
Process calibrators are essential tools for instrument technicians and calibration engineers in process plants, refineries, power stations and manufacturing facilities. The MS 7221 provides exceptional loop current accuracy with a built-in 24 V loop supply for 2-wire transmitter calibration without an external power source.
