WDHL- 100 Loop Resistance Tester

The loop resistance tester adopts 100A constant current output and is equipped with an automatic test function, which can automatically start and stop the test; automatically save the test data; it can perform continuous testing without operating the instrument, which greatly reduces the labor intensity.

The products are mainly used in the measurement of contact resistance of switch contacts and other micro-ohm resistances, with fast test speed and high accuracy.
