The Sonel MRU-200 earth resistance and soil resistivity meter for earth resistance and soil resistivity measurements with the use of various methods. The feature that definitely distinguishes this model from other meters of this kind is the use of all known methods of earth resistance measurement. The measurement can be carried out using the technical 3-pole and 4-wire method, also with additional clamps (multiple earthing), as well as the two-clamp method and the impulse method (earthing impedance measurement).
Compatible with ERP-1 adapter
ERP-1 adapter allows user to test earthing systems using flexible clamps. This is particularly useful, e.g. in case of lattice towers – there is no need to switch off the line or disconnect control connectors. Proprietary algorithm allows user to check the current direction in the individual measurements and facilitates damage detections, e.g. corroded steel strip (hoop).
Meter MRU-200 and adapter ERP-1 are sold separately.
