Focus on Compact, Handheld Earth Resistance Testers

In addition to the Sonel multi-function heavy duty tester MRU-120HD, Sonel also has an impressive range of affordable handheld, compact models.With 20mA test current these models give you more for you dollar than comparable brands.Below we highlight our 3 favourites the Sonel MRU-30, MRU-11 and MRU-10.

MRU-11 – Four Pole Earth Resistance Tester

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.
Unique to this lower priced model is the built-in maths capability, usually only found in expensive instruments. This function calculates soil resistivity in Ω-m from the resistance reading, eliminating a scientific calculator or using a spreadsheet. You only need to select the stake spacing in metres and the MRU-11 does the maths for you!Click here for further information & datasheet.

MRU-10 – Three Pole Earth Resistance Tester

Featuring:

3-pole Earth resistance to 10kΩ
2-pole Earth resistance to 10kΩ
Test Voltage 25/50V, Test Frequency 125Hz
Max Test Current 20mA
Resolution 10mΩ
Weatherproof to IP67

Includes Earth test kit and carry bag.Click here for further information, datasheet and pricing.
