Three Cup Insulating Oil Dielectric Strength Tester DYJY-III

1、 Product introduction

This instrument is a high-precision, fully digital industrial instrument developed by all the scientific research and technical personnel of our company according to the relevant provisions of the national standard GB507-1986 and the industrial standard DL/T846.7-2004, giving full play to their own advantages, after many on-site tests and long-term unremitting efforts. To meet the needs of different users, this series of instruments can be divided into single cup, three cups and multiple cups. The instrument is easy to operate and beautiful in appearance. Due to the use of fully automatic digital microcomputer control, it has high measurement accuracy, strong anti-interference ability, safety and reliability.

2、 Product characteristics

1. The instrument is controlled by a large capacity single chip microcomputer, which is stable and reliable;

2. The wide range watchdog circuit is set in the instrument to prevent the crash;

3. Multiple operation options. The instrument program is provided with two national standard methods (GB507-1986 and GB507-2002), industry standard DL/429, international standard IEC156 and user-defined operation, which can adapt to various choices of different users;

4. The oil cup of the instrument is made of special glass by one-time casting, which eliminates the occurrence of interference such as oil leakage;
