Earth Resistance Meters MTD 20KWe

Email

Product: Earth Resistance Meters
Model: MTD 20KWe
Manufacturer: SCOPE
Description

Overview

The MTD 20KWe earth is a digital and automatic Earth Resistance Tester, that allows to measure Earth Resistance (three pole) and Ground Resistivity by the Wenner�s (four pole) method.

Features

  • Built in Voltmeter for measurement of earth resistances of lightning conductors, pylons, substations, primary cabins, industrial and home installations.
  • Measurement of grounding resistances (with 3 terminals), soil resistivity (with 4 terminals) and spurious voltages present in the soil.
  • Equipment injects an electronically stabilized current in the soil and measures with high precision the voltage developed in the soil by means fo that current flowing through grounding diffusion resistance.
  • Equipment operates as a CA conventional voltmeter, making it possible to check the presence and to measure voltages generated by parasitic currents.
  • A sharp and intermittent audible signal indicates the abnormalities in the circuit.
