• MRU-10 is a simple meter that allows you to measure grounding by the use of the technical method and to measure grounding resistance by the use of the 2-pole and 3-pole methods. The instrument is easy to handle, resistive to interference, and highly accurate.

    MRU-10 is a basic device that allows 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.

    It allows to:

    • Measure earthing resistance using auxiliary electrodes 3 pole method,
    • Measurement of resistance of auxiliary electrodes RS and RH,
    • Measurement of interference voltage,
    • Measurement in the presence of interference voltage in the power network with frequency 50 Hz and 60 Hz,
    • Selection of maximum measuring voltage (25 V and 50 V),
    • Indication of battery state.

      The Sonel MRU-120HD Ground Resistance Tester in weather proof hard case allows the user to take earth resistance methods, using the 3-pole\n and 4-pole methods. Additionally, the MRU-120 offers selective earth resistance measurements, using an auxiliary clamp, meaning no influences\n from parallel earths or opening of junctions is required.

      \n

      It is possible to employ the Wenner method of measurement, the electrode and clamp method, for multiple earthing, or the two clamp method for\n measurements without the use of auxiliary rods. Additionally the MRU-120 will automatically calculate the resistance of electrodes and\n compensate for this reading for greater accuracy. Interference voltages and frequencies are measured with the MRU-120 to eliminate inaccuracies\n caused by these phenomena. The MRU-120 will calculate the distance between electrodes in metres or feet. When utilising a clamp for measurements,\n the MRU-120 can calibrate the used clamp. This instrument is built for accuracy and speed for professional measurements of various applications\n where ground resistance is required.

      \n

      The MRU-120HD is a professional grade instrument with all functions being selectable on its rotary dial. Being a menu driven instrument, all\n functions are clearly displayed on its large multifunction backlit graphical LCD display, with functions selected via the soft touch keys.\n Its’ ergonomic design permits the user to hang the meter for hands free use.
