Multifunctional earthing resistance meter
With the use of the presented earth resistance and soil resistivity meter Sonel MRU-120 it is possible to carry out earth resistance measurements using 3-pole and 4-wire method, measurements with the use of additional clamps (multiple earthing - without the necessity of unfastening the monitoring connections), as well as measurements using two-clamp method - in some cases it is possible to carry out the measurement without the necessity of using auxiliary probes driven into the ground. Sonel MRU-120 is a device designed to meet the needs of the power industry and used for earthing measurements - measuring range (measurements in accordance with EN 61557 standard) from 0.30 Ω. The functionality of the device is completed by the possibility to measure the resistivity of soil and the continuity of protective and equalising connections.
Measurement methods
Additional features
Application
MRU-120 meter was created for the most difficult working conditions. It generates a measuring current exceeding 200 mA, which provides effective measurements of grounding of energy objects such as transformer stations and power stations.
Thanks to the methods using clamps, it is not necessary to disconnect the control connectors, which is sometimes a very tedious operation. This plays a special role when performing works on objects exposed to weather conditions, where the connecting elements are sometimes corroded or tarnished. The graphical user interface provides clear readings and explicit messages. This translates into quick, trouble-free service.
Capabilities
The measuring methods available in the device allow for comprehensive control of working and protective grounding. The calibration function of the test leads eliminates the influence of their resistance on the result. However, this is just the beginning.

Multifunctional earthing and soil resistivity meter
The Sonel MRU-200 earth resistance and soil resistivity meter for earth resistance and soil resistivity measurements with the use of various methods.
The feature that definitely distinguishes this model from other meters of this kind is the use of all known methods of earth resistance measurement. The measurement can be carried out using the technical 3-pole and 4-wire method, also with additional clamps (multiple earthing), as well as the two-clamp method and the impulse method (earthing impedance measurement).
The use of the two-probe method allows the testing to be carried out without the need for additional auxiliary probes which are driven into the ground. The impact method, on the other hand, is used, among other things, to diagnose lightning protection earthing. It is also used for extensive, multiple and bonded earthing measurements (also underground). The advantage of this method is that there is no need to tamper with the circuit. The impact method enables measurements to be made in accordance with EN 62305 - the need to measure earth impedance.
This is not the end of the extended capabilities provided by the Sonel MRU-200 meter. The device additionally has the function of measuring the resistivity of soil, the continuity of protective and equalising connections, and, with the use of clamps, also leakage or fault currents.
Apart from the large number of functions and many measurement possibilities, the MRU-200 meter deserves recognition also for the high accuracy of the obtained results. Measuring range - measurements in accordance with EN 61557 - from as low as 0.30 Ω.
