The Sonel MRU-200-GPS earth resistance and soil resistivity 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).
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-GPS and adapter ERP-1 are sold separately.
