Product Description

The Sonel MRU-30 compact earth resistance and soil resistivity meter enables efficient and easy earth resistance measurement. Many measurement methods available in a small casing.

The MRU-30 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 the test.
