UT625A/UT625B 100A/200A Low Resistance Ohmmeter

The UT625A/UT625B Low Resistance Tester measures contact and loop resistance of switchgear with 100A/200A DC test currents. It directly reads resistance values, stores up to 200 test records, and uploads data to PC for storage/printing.
Featuring high accuracy and stable performance, it’s widely used in power systems, rail transit, new energy, etc., for loop resistance testing of high-voltage switches, transformers, busbars, cable joints, grounding devices, combiner boxes, and inverters.
