Resistance Tester

The Handheld Loop Resistance Tester is powered by a high capacity and high magnification lithium battery, with a compact design and handheld operation, making it easy to carry. A specialized testing equipment mainly used for measuring the contact resistance, loop resistance, and other micro ohmic resistance of switches, circuit breakers, and other equipment. Functional characteristics(Customisable) Adopting a 7-inch full color high-definition touch screen； Large output

Overview The DC resistance tester is an essential tool for testing inductive coils such as power transformers, mutual inductors, reactors, and electromagnetic operating mechanisms during manufacturing, factory inspections, installation, major repairs, post-tap-changer adjustments, acceptance tests, and preventive tests in the power sector. It can inspect the welding quality of winding joints, detect inter-turn short circuits, verify the proper contact of tap-changer positions
