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.
