Earth resistance tester MRU-30

continuityelectricground bond

The Sonel MRU-30 uses most known methods of earth resistance measurements. Tests can be performed using the 3-pole, 4-pole, 3-pole with auxiliary clamp and also, additionally, the MRU-30 employs the two clamp method of measurement, without the use of auxiliary test rods which can't be used in some situations. Complementary features of the MRU-30 are measurements of soil resistivity, continuity measurement of protective and equipotential conductors and, using clamps, leakage currents and interference voltages. Robust and weatherproof (IP65) - no ingress of dust, water protected by a nozzle against enclosure from any direction. Ergonomic casing - small and handy casing to make the measurements more convenient than before. Built-in rechargeable battery - saving time to replace flat batteries; can be recharged from Power Bank and Cigarette Lighter Socket! Clear on-screen notes - displayed on screen before and after the measurement to alert user of possible dangers and irregularities. Many measurement methods available in a small, portable casing.
