Sonel Test Measurement MRU-30

The Sonel MRU-30 is a rugged, portable tool for earth ground resistance measurements. Tests can be performed using the 2-pole, 3-pole, 4-pole, or 3-pole with current clamp methods. Additionally, the MRU-30 can perform the current clamp method using two clamps (one to generate, and one to measure current) for situations when test electrodes cant be used.

The MRU-30 provides measurements of soil resistivity, continuity measurement of protective and equipotential conductors, interference voltages, and with current clamp leakage current.
