EARTH RESISTANCE METERS

MRU-105 & MRU-106

The MRU-105 (for 50Hz) and MRU-106 (for 60Hz) are portable meters for the earth resistance and earth resistivity
measurement (Wenner’s method). The instruments can measure resistance using 2, 3, or 4 poles method. Measurements
can be simplified using current clamps. The very high immunity for existing interference voltage AC + DC at which
measurement is still performed: 24V (68V-p-p) but also measurement of existing interference voltage up to 40V is unique
functionality of the meters. Moreover meters measure the resistance of the probes and calculate automatically the error
coming from probe's resistances.
The meters MRU-105 (for 50Hz) and MRU-106 (for 60Hz) additionaly can be powered from Ni-MH batteries or
standard C size, and the test results can be stored in the internal memory and transmited to PC via USB - cable.
