UT625A 100A Low Resistance Ohmmeter

The UT625A Low Resistance Tester measures contact and loop resistance of switchgear with 100A 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.

Certifications: ROW
