Description

 

Basic grounding measurements under all conditions

The Sonel MRU-10 earthing resistance meter - a compact and easy to use meter designed for earthing measurements using the technical method and for earth resistance measurements using the bipolar method.

The handy Sonel MRU-10 meter is characterized by exceptional ease of use while providing accurate results. The device is highly resistant to the occurrence of interference voltages. This is a basic type of meter that allows the quality of the earthing system to be assessed based on the test results obtained. Due to its ergonomic shape, robust casing and large and easy to read display, the MRU-10 meter is ideal for use in various areas. The device is ideal for electrical installation work. It is also a suitable working tool for technicians and measuring engineers involved in checking earthing.
