  • 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.
