DC Ultra-Low Resistance Tester

DC resistance testers are core equipment in the field of electrical testing, widely used for DC resistance measurement of power transformers, high-voltage switches, motor windings, instrument transformers, and other equipment. Market demand is expanding significantly with the acceleration of electrification across multiple sectors.

In other industries, DC resistance testers have even broader application scenarios, such as resistance testing of ultra-long cables in the wire and cable industry, contact resistance measurement of connectors in the battery industry, and resistance measurement of printed circuit board traces and plated through-holes in electronics manufacturing.
