The MRU-120HD device enables assistance in measuring earth resistance:
- earth resistance measurement with 3-pole,4-pole method
- earth resistance measurement without disconnecting measured earths (using clamp)
- two clamps earth resistance measurement without auxiliary test probes
- continuity of equipotential bondings and protecting conductors
- earth resistivity measurement
The device is dedicated to earth measurements in the power industry – range of measurement in accordance with IEC 61557-5: 0,30 Ω… 19,9 kΩ.
The HD version of the MRU-120 meter means intended for difficult conditions, where there is no place for compromises. Is designed everywhere where instruments must be resistant to impact, splashing, mud and dust.
