I. Overview

Loop Resistance Tester is a product developed by our company.IECOur company, adhering to industry standards and national regulations, has meticulously developed high-precision, digital switch testing equipment leveraging our technical strengths. This equipment utilizes high-power constant current switch power supply technology, enabling the measurement of micro-ohm level contact resistance. It is widely applicable for measuring contact resistance, loop resistance, as well as cable wire and weld joint contact resistance in various switches and electrical appliances.

II. Performance Features

1. The test current is high, fully compliant with the national standards for test contact resistance.

2. High output voltage, wide measurement range.

3. The test current originates from a high-precision constant current power supply for large currents, requiring no manual adjustment and ensuring quick and accurate testing.

4. By employing a four-wire connection method, the impact of the test wire resistance on the test results has been effectively eliminated.
