200A Automatic Handheld Contact Resistance Tester
Application
1. High,middle and low voltage circuit breakers
2. High,middle and low voltage disconnecting switches
3. High-current bus bar joints
4. Cable&Welding joints
5. It is suitable for high current, micro ohm measurement.
Features
Output high-current continuously. Quick and accurate test. Test current is generated from high-precision 100A/200A switching mode constant current power supply, no need for manual adjustment.Adopts four-terminal wiring method. The influence of test line resistance on test results is effectively eliminated.Stable performance. There is over-heat protection crcuit designed for long-time working.Light weight, easy to carry and operate.
