MRU-30 earth resistance meter WMPLMRU30

The MRU-30 meter uses most of the known earth resistance measurement methods.

The device's capabilities are complemented by measurements of ground resistivity, continuity of protective and equipotential bonding and, using clamps, currents leakage and interference voltages.

• Strong and resistant to all weather conditions (IP65) - dustproof and resistant to water jets from all sides,
• Ergonomic housing - small and handy housing thanks to which measurements will be more convenient than before,
• Built-in battery - saving time of battery replacement, possibility of charging from PowerBank and car cigarette lighter.
• Clear messages - information displayed on the screen before and after after the measurement, they warn the user about possible dangers and irregularities,
• Many measurement methods available in a small housing.

Allows you to take measurements:

• earthing resistance using auxiliary electrodes,
• earthing resistance using auxiliary electrodes and clamps (for multiple earthing measurements),
• earthing resistance using double clamps (for earthing measurements when auxiliary electrodes cannot be used),
• ground resistivity (Wenner method),
• continuity of equipotential bonding and protective connections (meeting the requirements of PN-EN 61557-4 with auto-zeroing function - 200mA current).

Additionally:

• measurement of the resistance of auxiliary electrodes RS and RH
• interference voltage measurement,
• measurement in the presence of interference voltages 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) and feet (ft),
• memory for 990 measurements (10 banks of 99 cells each),
• calibration of measuring clamps,< /li>
• data transmission to a computer (USB),
• battery status indication.

Electrical safety:

• type of insulation double, in accordance with PN-EN 61010-1 and PN-EN 61557
