Earth resistance and resistivity meters

Discover the advantages of the Sonel MRU-12 - a new meter for measuring earth resistance and soil resistivity. The compact structure, durable and robust enclosure, many measurement methods and numerous functions make it perfect solution for demanding measurement conditions. Ergonomic enclosure and easy-to-clear display The Sonel MRU-12 enclosure is renowned for its ergonomics. The combination of plastic and rubber components prevents accidental slipping from the hand and provides protectio

Simple is better! When performing earth resistance measurements technical method is usually sufficient. It’s easy, provides us with precise reading and there is no need to invest in a sophisticated, expensive meter. Ordinary, inexpensive, single method earth resistance meter is suitable for most of the jobs. What if measurement conditions get a little complicated? The result of earth resistance measurement is the summary of resistance of the earthing (part of electrical system) and resisti

Now cheaper means better!   Earth resistance measuring is a process which requires much more involvement from the person carrying it out than any other measurements connected with electric shock protection. Therefore, each simplification that may help in performing the test correctly and reduces its duration cannot be overestimated. In the big family of earth resistance meters manufactured by Sonel SA, solutions which generally cover all available measurement methods can be found.

Measuring the earth resistance is a time-consuming process. Taking measurements requires a lot of commitment from the staff responsible. It depends on the grounding structure, terrain and many other objective factors. Both physical and mental commitment is needed. It is necessary to measure the grounding accurately without omitting any element of the measuring procedure. Taking shortcuts may result in such big errors that the whole measurement will have no metrological importance. It is obvio

The MRU-200 is a new earth resistance meter, designed and manufactured by Sonel, a Polish company. It is a highly functional instrument, suitable for users who have to make repeated measurements under various and often difficult field conditions. The meter provides an exceptional range of functions, including comprehensive methods for taking static earth resistance measurements (3 and 4-wire measurements; two types of clamp measurements), as well as a unique method of surge resistance measure

The technical method used widely for measuring earth resistance focuses on the measurement methodology, as well as on skills of the technician and his/her knowledge of the tested earthing circuit, because without it, even the best meter will not guarantee correct readings. On the other hand, even the best and most experienced professional will be unable to carry out proper measurements with incorrectly selected meter or instruments. Therefore, correctly performed earth resistance measurements r
