5.5.3 (5 ½) Digit Multi Function Calibrators

We are Manufacturer, Supplier, Exporter of 5.5.3 (5 ½) Digit Multi Function Calibrators, Multi Function Calibrators / Voltage & Current Standards and we are also specialized in Calibration Services. Our setup is situated in Pune, Maharashtra, India.

The Multi-Function Calibrator is useful for the calibration of Digital Multimeters, Clamp Meters, Digital Panel Meters, Analog Panel Meters, LCR Meters & Non-Contact Type Tachometers. It is a variable source with different ranges of DC Voltage, AC Voltage, DC Current, AC Current, Frequency, Resistance, Capacitance, Inductance & RPM (Non-Contact Type). It has been designed to calibrate the maximum ranges of a variety of models of multimeters available in the market. The calibrator gives very stable Output. Stability is suitable enough to calibrate 4^1/2 and 4^1/2 DMM and Clamp-on Meters. By using this source along with a high-resolution standard Multimeters user can calibrate even 5^1/2 DMM. Calibrator has a micro controller unit, which handles all the parameter selection and range selection logic. Micro controller drives to the set of relays as per the logic program. Relays rout the outputs.
