Universal grounding resistance tester

The withstand voltage tester is an instrument used to measure the withstand voltage strength of DF2670B AC/DC withstand voltage tester. It can intuitively, accurately, quickly, and reliably test the electrical safety indicators such as breakdown voltage and leakage current of various tested objects, and can be used as an AC (DC) voltage source to test the performance of original devices and the whole machine. The DF2670A, DF2670B, and DF2671A voltage withstand test product series are designed in accordance with domestic safety standards, with a voltage withstand range of 0-10kV and a leakage current range of 0-20mA. They are suitable for various household appliances, power supplies, transformers, terminal blocks, high-voltage rubberwood appliances, switch power plug sockets, motors, electronic instruments, instruments, etc. They are also essential voltage withstand experimental equipment for scientific research laboratories and technical supervision departments. DF2670A, DF2670B, DF2671A and other voltage endurance testers are all part of the digital display voltage endurance tester series, with digital displays for testing voltage, leakage current, and testing rooms.
