The SONEL MRU120HD Earth Test kit can perform Standard 2/3/4 Pole testing and Stakeless testing with the optional Test Probes. The high current output assures results even in bad soils.

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

SONEL MRU120HD Earth Test Kit

Multi-function Earth Test Set in weather proof Hard Case

Measurement of earth resistance (3-pole and 4-pole method)

Measurement of multiple earthing resistance (3-lead + clamp)

Measurement of multiple earthing resistance with use of 2 clamps

Earth resistivity measurement

It allows to take the measurements of:
- Earth resistance using auxiliary electrodes
- Earth resistance using auxiliary electrodes and clamp (for measurements of multiple earth)
- Earth resistance using double clamps (for measurement of earthing when it is impossible to use auxiliary electrodes), ground resistivity (Wenner method), measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 60364 - 6-61:2000 section 6.12.2) with auto-zero function – with current 200 mA.

Additionally:

Measurement of resistance of auxiliary electrodes RS and RH,

Measurement of interference voltage,

Measurement of interference frequency,

Measurement in the presence of interference voltage in the power network with frequency 50 Hz, 60 Hzelection of maximum measuring voltage (25 V and 50 V)

Introducing the distance between the electrodes for the resistivity in metres (m),

Memory of 990 measurements (10 banks of 99 cells each),

Calibration of clamp used,

Real time clock (RTC),

Data transmission to the computer (USB, wireless),
