Datasheet - Sonel - MMR-640

SKU: WMGBMMR640 Categories: , , Brand: Sonel


Designed to measure very low resistances of resistive types of objects. This product is made to be used in power plants, railways and maintenance companies, to measure welded and soldered connections, equipotential bondings, earthing conductors, contacts, bolted connections, windings of motors and power transformers and other resistive objects. MMR-640 can be also utilised on a production lines (eg. at the final production control stage). An innovative combination of a high-performance measuring device with a modern user interface and advanced data management system.
