High Precision Loop Resistance Tester

Product Overview
The High Precision Loop Resistance Tester is an intelligent measurement device designed for power systems. It utilizes DC 100A high - current output technology, combined with high - frequency switching power supplies and digital circuits, to accurately measure the contact resistance of high - voltage switches, circuit breakers, disconnectors, and other equipment. By breaking through the oil film and oxide layer between contacts, it ensures reliable test results, complying with industry standards DL/T845.4 - 2004 (China) and JJG1052 - 2009 (China), as well as international IEC standards.
