The loop resistance tester is a high-precision, digital switch testing instrument carefully developed by the company in accordance with IEC standards and relevant national regulations, using its own technical advantages. The instrument uses sine wave inverter, high-power constant current switching power supply technology, and can measure micro-ohm contact resistance. It is widely used in the measurement of contact resistance, loop resistance of various switches and electrical appliances, as well as contact resistance of cables, wires and welds.
