Product Description
Automatic Dielectric Breakdown Voltage of Insulating Liquids Tester
ASTM D877
Product model: JF507
Product Introduction
The instrument is formulated according to the ASTM D877 standard and designed in combination with the general requirements of the majority of users. The instrument is based on a single-chip microcomputer, which realizes all the automation of the test, high measurement accuracy, greatly improves the work efficiency, and greatly reduces the labor intensity of the staff. At the same time, the instrument has a small appearance and is easy to carry.

Main Feature
1. The instrument uses a microprocessor to automatically complete operations such as boosting, holding, stirring, static placement, calculation, and printing, and can perform oil circulation withstand voltage tests within the range of 0 to 100KV.
2. Large color screen LCD display, English character menu prompts.
3. The instrument is easy to operate, the operator only needs to make simple settings, and the instrument will automatically complete the pressure test of 1 cup of oil samples according to the settings. The breakdown voltage value and cycle times of 1 to 6 times will be automatically stored. After the test is completed, the thermal printer can print out the breakdown voltage value and average value of each time.
4. Power-off retention, can store 100 experimental results, and can display the current ambient temperature and humidity.
5. The single-chip microcomputer is used to control the voltage at a constant speed, and the voltage and frequency are accurate to 50HZ, which makes the whole process easy to control.
6. It has overvoltage, overcurrent, limit and other protections to ensure the safety of operators.
7. With temperature measurement display function and system clock display.
8. Standard RS232 interface, can communicate with computer.
