ZRY-III Contact Resistance Tester
Overview
ZRY-Ⅲ contact resistance tester is our new generation of product, which controlled by Single-Chip Microcomputer and has a LCD display. Compared with similar products, it has unique advantages such as small size, light weight, fast measurement, easy reading, etc.
Main properties
Easy operate;
Press only one button to start the measurement;
Reproducible, measurement of dozens of micro-ohm low resistance can give a result with many decimal digits;
Better accuracy and resolution than testers simply using digital meter;
Single-Chip Microcomputer precisely control the electrify time of 100A current to ensure adequate heat dissipation of the constant current source, which is good for the equipment longevity.
