Three-phase Loop Resistance Tester

I. Introduction

Three phase Loop Resistance Tester adopts the advanced high-power switching power supply technology and advanced electronic circuit. It is the dedicated tester for the resistance of high and low switch, cable wire and welding joint. It can measure the resistance value of being tested object under standard current status. This contact resistance tester is with small the advantages of dimension, light weight, strong anti-interference, high precision, easy operation and perfect function protection and so on.

Nick name: contact resistance tester, loop resistance tester, contact resistance meter, loop resistance meter, contact resistance test kit,loop resistance test kit.
