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.
