Product Description

GDHL-300B DC 300A Weld Electrical Switches 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
 

1. Output high-current continuously.
2. Quick and accurate test. Test current is generated from high-precision 100A/200A switching mode constant current power supply, no need for manual adjustment.
3. Adopts four-terminal wiring method. The influence of test line resistance on test results is effectively eliminated.
4. Stable performance. There is over-heat protection crcuit designed for long-time working.
5. Light weight, easy to carry and operate.
