SONEL-MMR-640 Microohmmeter

• measurement of very low resistance
• high immunity to disturbances
• easy operation
• big touchscreen
• automatic measurement mode
• autoranging

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).

The MMR-640 meter provides an innovative combination of a high-performance measuring device with a modern user interface and advanced data management system.

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.

The MMR-640 meter is equipped with a readable colour 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.
