Product Overview

ED0303B-600The High-Precision Circuit Resistance Tester, also known as the Contact Resistance Tester or the High Current Micro-Ohmmeter, is primarily used for the high-precision measurement of contact resistance in circuit breakers and resistance of current-carrying conductors. It can maintain a stable output of current over a long period of time and meetsDL\T845.4-2004Regulations related to "General Technical Conditions for Resistance Measurement Devices, Part 4: Circuit Resistance Meters."

ED0303B-600The high-precision loop resistance tester can continuously output high current, effectively overcoming the drawbacks of "pulsed" power sources that cannot work continuously on the workbench and cannot effectively penetrate the "oxide film" of the tested product. The measurement resolution can reach0.1μΩ。

ED0303B-600The high-precision loop resistance tester boasts measurement functions on par with imported products. It is widely used for high-precision measurements of contact resistance (loop resistance) in high-voltage switches and is also suitable for other applications requiring large current and micro-resistance measurement methods.
