DIGITAL EARTH RESISTANCE TESTER
ERT-1501
ERT-1501R
INTRODUCTION
The Metravi ERT-1501 is an electronic, digital, earth resistance tester and a
direct replacement or the conventional hand generator type tester for 0 – 10 /
100 / 1000Ω, and features 4 Terminals with a Testing Kit and Cables in a hard
carrying case.
The device measures Earthing used in electrical equipment as well as Ground
Resistivity. It can also be used for measurements of the other low regular and
liquid resistances, as well as AC Voltage, DC Voltage and Resistance. The
tester finds wide application for testing earthing installations in industries
like Power, Telecommunications and Electrical Traction Systems.
Rechargeable battery option is available at extra cost.
