    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.
