100A/200A Highly Accurate and Intelligent Loop Contact Resistance Tester Set Contact Resistance Tester Ohm Meter

Product Description

Product Description
Products introduction This loop resistance tester is a high-precision and digital switch testing instrument developed by our company according to IEC standard and the latest electric power executive standard of the people's Republic of China DL/T845.4- 2004, giving full play to our own technical advantages.The Contact Resistance Meter adopts high frequency and high power constant current switching power supply technology, which can measure micro ohm contact resistance.
It is widely used to measure the contact resistance, loop resistance of various switches and electrical appliances, and the
contact resistance of cables, wires and welds.
The Contact resistance tester has accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switch maintenance of electric power and power supply departments and loop resistance test of high-voltage switch factory.
