Sonel MMR-650
Micro-Ohm Meter, 10A Measure winding resistance and low resistance
The Sonel MMR-650 is a low resistance and winding resistance meter designed to measure small resistances of resistive and inductive objects. It can be used to measure the resistance of both transformer windings – including amorphous-core transformers – and resistive objects. The MMR-650 meter is dedicated to use in power plants, maintenance companies and railway industry, among others.
Product features
- Measurement of winding resistance (inductive objects including amorphous core transformers)
- Measurement of very low resistance
- Transformer core demagnetization function
- Automatic temperature compensation function (temperature probe)
- Function of determining the temperature of a motor under load
- High immunity to disturbances
