Description

 

 

Low resistance within range

 Product features

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

 

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 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.
