This instrument is designed and manufactured in accordance with the national standard GB/T507 and the electric power standard DL429.9. It is suitable for testing the degree of physical contamination of insulating oil by water and other suspended substances, and is widely used in electric power, petroleum, chemical industry and other industries.

Main features:

1. Adopt microprocessor automatic control, with automatic voltage boosting, maintaining, stirring, standing, calculating, printing and other operations. It can carry out oil circulation withstand voltage test within the range of 0～80KV.

2. The breakdown voltage values and cycle times of 1～6 times will be automatically stored. After the test is completed, the thermal printer can print out the breakdown voltage values and average value of each time.

3. Power-off retention function, which can store 100 test results, and can display the current ambient temperature and humidity.

4. Equipped with overvoltage, overcurrent, limit and other protections to ensure the safety of operators.
