HM803 Insulation Oil Breakdown Voltage Tester

Product Description


This instrument is a high-precision and fully digital industrial instrument carefully developed by all our company's scientific research and technical personnel, in accordance with national standards and relevant regulations of industry standards, leveraging their own advantages, after multiple 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 cup and multi cup models. The instrument is easy to operate and has a beautiful and elegant appearance. Due to the use of fully automatic digital microcomputer control, the measurement accuracy is high, the anti-interference ability is strong, and it is safe and reliable.


  1. The instrument is controlled by a large capacity microcontroller, ensuring stable and reliable operation;
  2. The instrument is equipped with a wide range watchdog circuit to prevent crashes;
  3. Multiple operation options, the instrument program has two national standard methods, GB507-1986 and GB507-2002, industry standard DL/429, international standard IEC156, and custom operations, which can adapt to various choices of different users;
  4. The instrument oil cup is cast with special glass in one go to prevent interference such as oil leakage;
  5. The unique high-voltage sampling design of the instrument allows the test values to directly enter the A/D converter, avoiding errors caused in analog circuits and making the measurement results more accurate;
  6. The instrument has functions such as overcurrent, overvoltage, short circuit protection, etc. internally, and has strong anti-interference ability and good electromagnetic compatibility.
