Earth resistance and ground resistivity meter MRU-120 WMPLMRU120

The MRU-120 device offers earthing resistance measurements using the technical method (3p, 4p).

The device is dedicated to earthing measurements in the power industry - measuring range (measurements in accordance with the PN- EN 61557) from 0.30 Ω.

The capabilities of the device are supplemented with measurements of ground resistivity, and continuity of protective and equipotential bonding.

Additionally:

• measurement of the resistance of auxiliary electrodes RS and RH,
• measurement of interference voltage,
• measurement of the frequency of interference signal,
• measurement in the presence of interference voltage in networks with a frequency of 50 Hz and 60 Hz,
• selection of the maximum measurement voltage (25 V and 50 V),
• entering the distance between the electrodes for resistivity in meters (m),
• memory for 990 measurements (10 banks of 99 cells each),
• calibration of applied clamps,
• real time clock (RTC),
• data transmission to a computer (USB or wireless),
• battery status indication.

Measurement category: CAT IV 300V (CAT III 600V)
