Sonel MRU-200 Earth Resistance & Resistivity Meter

The Sonel MRU-200 Earth Resistance & Resistivity Meter is an earth tester that can utilise every measurement method to determine earth resistance. It is available with or without built-in GPS; please see the table below for further information.

The Sonel MRU-200 Earth Resistance & Resistivity Meter supports the following measurement methods and functions:

Earth resistance measurement using a 2-pole, 3-pole and 4-pole method
Selective earth resistance measurement using a clamp (no influence from parallel earth and the opening of junctions is not required)
Impulse earth resistance measurement with three kinds of measuring impulse: 4/10µs, 8/20µs and 10/350µs
Two-clamps earth resistance measurement without auxiliary test probes
Earth resistance using auxiliary electrodes and/or a clamp
Impulse earth resistance
Ground resistivity using the Wenner method
Resistance of auxiliary electrodes RS and RH
Leakage current
Current using a clamp or flexible clamp 
Continuity of equipotential bondings and protective conductors with an auto-zero function and 200mA current (meets the requirements of IEC 60364-6-61:2000 section 6.12.2)
Interference voltage
Interference frequency
