100A Loop Resistance Tester: is designed by combining digital circuit technology and switching power supply technology. It is suitable for measuring contact resistance and loop resistance of switch control equipment. The test current adopts the DC 100A recommended by national standards. It can directly measure loop resistance and contact resistance at a current of 100A, and display them digitally. This instrument has accurate measurement and stable performance, meeting the requirements of on-site high-voltage switch maintenance in power and power supply departments, as well as loop resistance testing in high-voltage switch factories.

Product Features
1. High current: Using the latest power supply technology, it can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse power supplies, effectively breaking through the oxide film on switch contacts, and obtaining good test results
2. Strong anti-interference capability: Under severe interference conditions, the last digit of the LCD screen can stabilize within ±1 digit, with stable readings and good repeatability
3. Long service life: All high-precision resistors are used, effectively eliminating the influence of ambient temperature on measurement results, while enhancing vibration resistance
4. Easy to carry: small size, light weight
