The MMR-650 is a compact, portable microohmmeter for measuring very low resistances of resistive and inductive objects. This product is designed to measure welded and soldered connections, equipotential bondings, earthing conductors, contacts, bolted connections, windings of motors and power transformers, including amorphous core transformers. The MMR-650 can be also deployed on production lines in manufacturing industries. Its 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. An optional printer can print labels to identify test items, or print results in the field.
