KDHL-100 circuit resistance tester is designed by combining digital circuit technology and switching power supply technology. It is suitable for the measurement of contact resistance and loop resistance of switch control equipment.

Functional features:
1. High current: By adopting new power supply technology, it can continuously output high current for a long time, overcoming the drawback of instantaneous current in pulse power supplies. It can effectively break through the oxide film on the switch contacts and achieve good test results.
2. Strong anti-interference ability: Under severe interference conditions, the last digit data on the LCD screen can remain stable within ±1 digit, ensuring stable readings and good repeatability.
3. Long service life: All high-precision resistors are adopted, effectively eliminating the influence of environmental temperature on the measurement results. Meanwhile, the use of high-quality connectors enhances the anti-vibration performance.
4. Portable: Small in size and light in weight.
