1.Overview
This type of insulating oil dielectric strength tester is a high accuracy and full digital industrial instrument developed by all scientific research and technical personnel of our company according to the relevant standards and regulations of insulating oil test, giving full play to their own advantages, after many field tests and long-term unremitting efforts. The machine is easy to operate and beautiful. Due to the use of fully automatic digital microcomputer control, so the measurement accuracy is high, anti-interference ability is strong, safe and reliable.
2.Instrument features
1) The instrument is controlled by a large-capacity single-chip microcomputer, which is stable and reliable;
2) Temperature, humidity and clock display function;
3) Infrared oil temperature measurement (for buyer’s option);
4) Wide range watchdog circuit is set in the instrument to eliminate the crash;
5) Multiple operation options. The instrument program is equipped with GB507-1986, GB507-2002, DL429.9, IEC156 standard methods and user-defined operations, which can adapt to various choices of different users;
6) The oil cup of the instrument is cast with special glass and polymer materials at one time to prevent oil leakage and corrosion;
7) The unique high voltage sampling design of the instrument allows the test value to enter the A/D converter directly, avoiding the error caused in the analog circuit and making the measurement results more accurate;
8) The instrument has functions such as overcurrent, overvoltage, short circuit protection, and has strong anti-interference ability and good electromagnetic compatibility;
9) Switch between Chinese and English to meet different customer needs;
10) Analyze its own data to help users judge the quality of oil products;
11) RS232 data transmission;
12) Portable structure, easy to move, easy to use both indoors and outdoors.
13) Wide LCD color touch screen display
