200A Loop Resistance Tester ,IEC 62271 Contact Resistance Tester for High Power UPS System Safety Inspection

Circuit resistance tester adopts the national standard requirement of 200A DC constant current to continuously measure resistance with an accuracy of 0.5% RGD+0.05% FS. Not only can it be tested in harsh outdoor environments with temperatures ranging from -10 ℃ to 40 ℃, but it can also work in tropical rainforests with relative humidity<80%.

The equipment is commonly used to measure the contact resistance of conductive circuits such as high-voltage switches, circuit breakers, bus ducts, cable joints, etc., which can effectively prevent local overheating, burning or power accidents caused by poor contact.
