Overview
Enviro Test Construct ohm ground resistance tester is a multifunctional earth resistance or earth resistivity tester equipped with a microcomputer. It employs digital signal settlement technology, which can draw earth measurement signals, possess features of high frequency, high accuracy and high resistance, and measure earth resistance or earth resistivity accurately. The instrument can execute standard 3 POLE and 4 POLE earth resistance measurements and has 2POLE earth resistance measurement and earth resistivity calculation functions as well.
