    Overview of MRU-10 Earth Resistance Meter

    The Sonel MRU-10 is a simple meter that allows you to measure earthing resistance using a technical method as well as measure grounding resistance using the pole method. The instruments is easy to handle, resistive to interference, and highly accurate. This unit allows checking the quality of the grounding system on the basics of the received measurement result. The device is simple to operate and intuitive and an excellent choice for electrical  technicians, installations contractors and professionals dealing with grounding measurements. This Earth Resistance meter is durable with firm housing, as well as big and clear display with ergonomic design makes this instrument ideal to use both in the field and most working environments.

    Overview of  MRU-200 Earth Resistance meter

    The MRU-200 earth resistance meter is a unique meter in the market, which uses all measurement methods to get earth resistance.  Making sure the ground system has a low earth ground resistance when initially installed is a very important safety check, but making sure the  low resistance is maintain is just as important. Resistance of grounding system might increase when the ground rods are corroded. Over time soil with high moisture, salt content and high temperatures will corrode connections.  It is therefor recommended that the earthing be checked periodically to make sure there is not an big increase in resistance.
