Description
Fields of application
The ground resistance measuring device MRU-30 is used for measuring single and multiple earthing with the use of auxiliary electrodes and/or pliers. It is also possible to measure the specific ground resistance (WennerMethod) and check the continuity of equipotential connections and protective conductors.
Properties
The measuring device enables the conduct of earthing tests mainly with the technical methods. Thanks to its high immunity it can also deal with interference currents under difficult conditions in circuits
system. The simple and intuitive operation simplifies and speeds up the measurement process. The measuring device has an internal memory. The measurement results can be transferred to a computer for data processing and the creation of documentation.
Robust and practical housing
The ergonomic, small and practical casing enables a comfortable and simple operation. The measuring device is resistant to harsh weather conditions. The protection class IP65 guarantees dust resistance and resistance to water jets from all sides. The rechargeable battery is permanently installed and can be charged using a power bank or the cigarette lighter in the car.
