The MMR-650 is a compact, portable winding resistance and low resistance meter for measuring very low resistances of resistive and inductive objects (windings).
This product is made to be used in power plants, railways and maintenance companies, to measure windings of power transformers and motors, breakers, contacts, earthing conductors, equipotential bondings, welded and soldered connections, bolted connections, and other resistive and inductive objects. The MMR-650 can be also deployed on production lines in manufacturing industries.
It's rugged enough for field work in power plants and maintenance yards; it comes with an IP54 rating, and will perform well in extreme temperatures (-10°C to 50°C). Sonel has made several design innovations with the MMR-650; it is a high-performance measuring device with a modern user interface, and advanced data management to store results. It can be connected to a PC or network via WiFi for creating reports.
