200A Contact Resistance Tester
The SXHL-200A High Current Contact Resistance Tester is designed for measuring contact resistance and circuit resistance of electrical conductive connections. It is widely used for testing circuit breaker contacts, switchgear conductive circuits, cable connections, and welding joints.
According to IEC standards and relevant testing regulations, high DC current testing is required for accurate contact resistance measurement. This tester adopts 50A/100A/150A/200A selectable test current output and four-terminal measurement technology to reduce the influence of test lead resistance and improve measurement accuracy.
