The Sonel MRU-11 earth resistance and soil resistivity meter
is a simple meter that allows for measuring the earth resistance
using the 3 pole and 4 wire method and the soil resistivity using
the Wenner method. The instrument is easy to use, interference
resistant and highly accurate.
MRU-11 is a basic device which, on the basis of the measurement
result obtained, allows for checking the quality of the earthing
system. With its ergonomic design, durable and robust casing
and
large, easy-to-read display, the meter is ideal for use in the field
as well as in most work environments.
The device is simple to use and intuitive. It is the best choice for
electrical contractors, technicians and earthing measurement
professionals.

Overview
MRU-11 is a
simple meter that allows you to measure grounding by the use of the
technical method (3- and 4-wire) and soil resistivity by Wenner
method. The instrument is easy to handle, resistive to interference,
and highly accurate.
MRU-11 is a basic
device that allows for checking the quality of the grounding system
on the basis of the received measurement result. Its ergonomic
shape, durable and firm housing, as well as big and clear display
make this instrument ideal to use both in the field and most working
environments.
The device is simple to operate and intuitive. It is the best choice
for electrical installations contractors, technicians, and
professionals dealing with grounding measurements.
