Product Features

1.With a microprocessor, three cups of a body, automatically fulfill the withstand voltage test for oil circulation with a range of 0～80KV (including boosting, maintaining, mixing, standing, calculation, printing and other operations)

2.Display by large-screen LCD and prompt by Chinese menu.

3.The instrument has the advantages of simple operation, the operators only need a simple setup, instrument will automatically set in accordance with 1-3 oil sample pressure test. Each oil sample, each breakdown voltage value and the number of cycles will be automatically stored, after completion of the test, the thermal printer can print out the breakdown voltage value and average value.

4.Maintain power down, can store 100 experimental results, and can display the current environment temperature and humidity.

5.Using single chip microcomputer control speed boost, voltage frequency accuracy to 50HZ, makes the whole process easy to control.

6.Equipped with over-voltage, over-current and limit protections to ensure the safety of operators

7.With the function of displaying the measured temperature and system clock.

8.Communicate with computer with a standard RS232 interface.
