Description

MRU-200 GPS Meter with XL3 case

The Sonel MRU-200-GPS meter is a versatile meter for earth resistance and soil resistivity measurements. The device allows the use of all known earth resistance measurement methods. This renders it an unrivalled measuring instrument in its category and definitely makes it stand out from other devices of its kind. Sonel MRU-200-GPS allows you to perform tests with the 3-pole and 4-wire method, using additional clamps (multiple earthing), as well as the two-clamp method and impulse method (earth impedance measurement).

The application of the two-core measurement method allows, under certain conditions, to perform earth resistance measurements without the use of auxiliary probes which are driven into the ground. The impact method, on the other hand, is used for diagnosing lightning protection earthing, but can also be used to measure extensive, multiple and connected earthing (including underground) without interfering with the circuit. With the use of the impact method it is possible to carry out measurements in accordance with EN 62305 – the need to measure earth impedance. It is worth noting that the instrument also has a built-in GPS receiver, which allows for recording the result along with the coordinates of the location. An additional function of the meter is the possibility of carrying out measurements of soil resistivity, continuity of protective and equalizing connections and, with the use of clamps, also leakage or fault currents.

The high class of the device is confirmed by the excellent accuracy of the result it produces. The meter makes measurements in accordance with the EN 61557 standard starting from 0.100 Ω.
