Application
The MMR-640 meter is designed to measure very low resistance of resistive objects. This product is made to be used in power plants, railways and maintenance companies to measure resistance of:
- breakers, contacts,
- earthing conductors, equipotential bondings,
- welded and soldered connections,
- bolted connections,
- and other resistive objects. MMR-640 can be also utilized on production lines (eg. at the final production control stage).
Device capabilities
The MMR-640 meter provides an innovative combination of a high-performance measuring device with a modern user interface and advanced data management system.
Durable and practical casing
In response to the customers needs the MMR-640 has been designed to operate in difficult environmental conditions. A unique casing with the IP67 ingress protection rating ensures that the device is both waterproof and dustproof.
Easy readout
The MMR-640 meter is equipped with a readable color touchscreen that, due to its 800 x 480 pixel resolution, provides both high comfort of interacting with the interface and high readability of the measurement results.
