Product description

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.

Manufacturer's description

Universal earth tester

The Sonel MRU-30 compact earth resistance and soil resistivity meter enables efficient and easy earth resistance measurement. Many measurement methods available in a small casing.

The MRU-30 meter is surprisingly versatile in nature. The instrument can be used to perform single earthing measurements as well as multiple earthing measurements using additional clamps or electrodes. Additional capabilities of this handy device include measurement of soil resistivity using the Wenner method, as well as verification of the continuity of equalising connections and protective conductors. Another advantage of the Sonel MRU-30 meter is the clear transmission of information alerting the user to possible dangers or detected irregularities. Information appears on the screen both before and after the test.

Measurement methods

3-pole and 4-wire method – measurement of earthing systems using auxiliary probes
3-pole method with clamp – measurement of earthing systems with multiple earth electrodes
Two-clamp method – measurement of earthing system when the auxiliary probes cannot be used
Earth resistivity – Wenner method
Resistance of earth connection and equipotential bonding measured using current ≥200 mA with auto-zero function – meets the requirements of EN 61557-4

Features

Measurement of auxiliary electrode resistances R_S and R_H
Measurement of interference voltage
Measurement in the presence of interference voltages in networks with frequencies of 50 Hz and 60 Hz
Selection of maximum measurement voltage (25 V and 50 V)
In ground resistivity measurements, distances between electrodes can be input in meters (m) or feet (ft)

Application

The MRU-30 earth resistance meter is designed to measure single and multiple earthings using auxiliary electrodes and/or clamps. Moreover it is possible to measure ground resistivity (Wenner method) and verify the continuity of equipotential bondings and protective conductors.

Capabilities

The meter provides the ability to make grounding tests with all kinds of the technical method. High immunity to interference allows it to be used even in difficult conditions in circuits with interfering currents. Simple and intuitive operation makes the measurements easier and faster. The meter has internal memory. The measurement results can be transmitted to a computer for data processing and preparation of documentation from the grounding tests.

Durable and practical casing

Ergonomic, small and practical housing allows comfortable and easy operation. The meter is resistant to all weather conditions. IP65 ingress protection guarantees dustproof and resistance to water jets on each side. The battery is permanently built-in and can be charged from a PowerBank or car cigarette lighter.
