  • Product Introduction

ZC-265B is a tool DC resistance tester newly developed by our company with its own technical advantages. This instrument is an innovative product with small volume, hand-held operation, battery power supply and easy to carry. It has the characteristics of small size, light weight and large output current. The whole machine is controlled by a single chip microcomputer, which automatically completes the functions of self inspection, data processing, display, etc. it also has the functions of automatic discharge and discharge audible alarm indication. The instrument has high measurement accuracy and simple operation, and can realize the rapid measurement of transformer DC resistance.
