Earth resistance and soil resistivity meter MRU-200-GPS WMPLMRU200GPS

The MRU-200-GPS meter (as the only one in the world) uses all known earth resistance measurement methods, which definitely distinguishes it from other devices. It has a built-in GPS receiver - saving the result with location coordinates.

Allows you to perform measurements of:

• earth resistance using auxiliary electrodes,
• earthing resistance with the use of auxiliary electrodes and clamps (for the measurement of multiple earthings),
• earthing resistance with the use of double clamps (for earthing measurements when the use of auxiliary electrodes is not possible),
• earthing using the impulse method (without the need to disconnect the measured earth electrodes),
• earth resistivity (Wenner method),
• current using clamps (e.g. leakage) and flexible clamps (coil Rogowski)
• fault currents,
• measurement of continuity of equipotential bonding and protective connections (meeting the requirements of PN-EN 60364 - 6-61:2000 point 6.12.2) with auto-zeroing function - current 200 mA .

Additionally:

• measurement of resistance of auxiliary electrodes RS and RH,
• measurement of interference voltage,
• measurement of the frequency of the interfering signal,
• measurement in the presence of interfering voltages in networks with the frequency of 16 2/3 Hz, 50 Hz, 60 Hz and 400 Hz (with automatic selection of the appropriate frequency of the measurement signal or manual selection),
• selection of the maximum measurement voltage (25 V and 50 V),
• entering the distance between the electrodes for resistivity in meters (m) and feet (ft),
• memory for 990 measurements (10 banks of 99 cells each),
• calibration of applied clamps,
• real time clock (RTC),
• data transmission to USB computer,
• battery status indication.

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