The MRU-120HD meter allows the measurement of earth resistance:
earth resistance measurement with 3-pole and 4-pole method,
earth resistance measurement without disconnecting the measured earths (using a clamp),
earth resistance measurement with two clamps without auxiliary test probes,
continuity of equipotential links and protective conductors,
earth resistivity measurement.
The device is dedicated to earth measurements in the energy industry: measurement range according to IEC 61557-5: 0.30 Ω … 19.9 kΩ.
The HD version of the MRU-120 meter means for tough conditions, where there is no room for compromises. It is designed for use in all places where instruments need to be resistant to impact, splashes, mud and dust.
