Sonel MRU-30

Earth Resistance and Resistivity Meter

  • Measurement of auxiliary electrode resistances RS and RH
  • Measurement of interference voltage
  • Measurement in the presence of interference voltages in networks with frequencies of 50 Hz and 60 Hz
  • Selection of maximum measurement voltage (25 V and 50 V)
  • In ground resistivity measurements, distances between electrodes can be input in meters (m) or feet (ft)

Available on back-order

The Sonel MRU-30 compact earth resistance and soil resistivity meter is surprisingly versatile in nature. The instrument can be used to perform single earthing measurements as well as multiple earthing measurements using additional clamps or electrodes. Additional capabilities of this handy device include measurement of soil resistivity using the Wenner method, as well as verification of the continuity of equalising connections and protective conductors. Another advantage of the Sonel MRU-30 meter is the clear transmission of information alerting the user to possible dangers or detected irregularities. Information appears on the screen both before and after testing.
