YNYSZ-H oil acid value automatic tester is a high-accuracy, fully digital industrial instrument carefully developed by our company's scientific research and technical personnel, according to the relevant regulations of the national standard, giving full play to their own advantages, and after long-term unremitting efforts. The machine is easy to operate and beautiful in appearance. The instrument adopts fully automatic digital microcomputer control, takes the acid-base neutralization reaction of chemical analysis as the basic framework, and is equipped with self-developed background blank deduction and titration end point logic judgment program, so the precision and accuracy of the measurement are relatively ideal.

Transformer and turbine oil acid value detection is a routine inspection item for power systems and oil-filled electrical equipment in industrial and mining enterprises. The acid value tester is a device developed by our company for the above-mentioned oil acid value measurement. The instrument takes a single-chip microcomputer as the core, and integrates multidisciplinary technologies such as light, mechanics, electricity and chemistry. It basically completely replaces manual operation, which improves work efficiency, reduces the labor intensity of operators, and minimizes the harm of organic solvents and other chemicals to the human body.

The YNYSZ-H oleic acid value automatic tester adopts the principle of neutralization method. Under normal temperature, the microcomputer control automatically completes the addition, stirring, titration and end point judgment. The touch LCD screen is used to select all working parameters, the man-machine dialogue interface is simple and friendly, and the operation is convenient. The average oil sample analysis cycle is about 2 minutes. Up to 35 groups of measurement results can be displayed separately, and a number of measurement-related parameters can be printed out.

A special reagent bottle is used to hold the extraction liquid and the neutralization liquid. The extraction liquid is stored in glass containers to ensure that there is no plastic additive contaminants. The neutralization solution is stored in polyethylene plastic bottles, which completely avoids the possibility of caustic potassium reacting with glass. In addition, the company has developed a neutralized liquid equilibrium gas and solid purification device, which completely avoids the influence of carbon dioxide and water vapor on the concentration of the neutralized liquid, and will not make mistakes in using high-concentration caustic potassium or caustic soda purification solutions as titration Accidents in the use of standard solutions. During the working process, the user does not need to touch the organic solvent by hand, which reduces the harm of chemicals to the human body.

According to user needs, the acid value tester can measure 1 to 3 samples respectively.
