ZXHL-200A DC Switchgear Contact Resistance Tester with 200A Output and 1μΩ Resolution for High-Voltage Maintenance
The ZXHL-200A Contact Resistance Tester is engineered for precise measurement of contact resistance in switching control equipment. Utilizing advanced high-frequency switching power supply technology and digital circuit systems, this instrument delivers exceptional accuracy and stability for high-voltage switch maintenance and factory testing applications.
- High Current Output: Continuous DC output up to 200A effectively breaks down oxide layers on switch contacts for accurate measurements
- Strong Anti-Interference: Maintains measurement stability (±1d error) even in electrically noisy environments
- Extended Service Life: Precision resistors minimize temperature impact while military-grade connectors enhance vibration resistance
- Portable Design: Compact 380×350×260mm dimensions and 10kg weight ensure easy field deployment
