Description
The Sonel MRU-12 is the easy way to measure earthing and soil.
The Sonel MRU-12 earth resistance and soil resistivity meter is a simple meter that allows you to measure grounding by using the technical method (3-pole and 4-wire) and soil resistivity by Wenner and Schlumberger method. The earth tester is easy to use, resistive to interference, and highly accurate.
MRU-12 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.
