The KDHL-100 Loop Resistance Tester is a precision instrument developed by Kegang Power & Electric using advanced high-power switching power supply technology and sophisticated electronic circuits. It is specifically designed for measuring the resistance of high/low voltage switches, cables, wires, and weld seams. The tester uses a 100A DC current as recommended by the national standard GB736, allowing it to measure the resistance value of the test specimen under a 100A current condition. This device features a compact size, lightweight, strong anti-interference capability, high accuracy, convenient operation, and comprehensive protection functions.

1. High Current: The loop resistance tester employs the latest power technology to continuously output high current over extended periods, overcoming the limitations of pulse-type power supplies that provide only momentary high current. This capability effectively breaks through the oxide film on switch contacts, yielding excellent test results.

2. Strong Anti-Interference Capability: Under severe interference conditions, the last digit on the LCD screen can remain stable within ±1 digit, ensuring stable readings and good repeatability.

3. Long Service Life: Utilizes high-precision resistors throughout, effectively eliminating the impact of environmental temperature on measurement results. Additionally, the use of military-grade connectors enhances vibration resistance.

4. Portable: Compact size and lightweight design make it easy to carry.
