The BOHL-200 circuit resistance tester is designed based on the latest power implementation standard DL/T845.4-2004 of the People's Republic of China, using a combination of high-frequency switching power supply technology and digital circuit technology It is suitable for measuring the circuit resistance of switch control equipment The test current adopts the recommended national standard of 100A and 200A DC. The circuit resistance can be directly measured at 100A current or 200A current, and the final test results are displayed in numbers The instrument measures accurately and has stable performance, meeting the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing for power and supply departments

Loop Resistance Tester, Loop Contact Resistance Tester, Digital Loop Resistance Tester, High Voltage Loop Resistance Tester, Contact Resistance Tester

1. High current: Using the latest power technology, it can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse power supplies. It can effectively penetrate the oxide film of switch contacts and obtain good test results

2. Strong anti-interference ability: Under severe interference conditions, the last bit of data on the LCD screen can remain stable within ± 1 word range, with stable readings and good repeatability

3. Long service life: All use high-precision resistors, effectively eliminating the influence of environmental temperature on measurement results. At the same time, the use of military connectors enhances the anti vibration performance
