WX-SZ Transformer Oleic Acid Value TesterUsing the principle of neutralization, at room temperature, the microcomputer controls the automatic completion of liquid addition, stirring, titration, and endpoint determination. Adopting a touch sensitive LCD screen to select all working parameters, the human-machine dialogue interface is simple and friendly, easy to operate, and the average oil sample analysis cycle is about 2 minutes. It can display up to 35 sets of measurement results separately and print out multiple parameters related to the measurement.

Special reagent bottles are used to contain extraction and neutralization solutions. The extraction solution is stored in a glass container to ensure no plastic additive pollutants. The neutralization solution is stored in polyethylene plastic bottles, completely avoiding the possibility of reaction between caustic potassium and glass. In addition, we have independently developed a neutralization liquid equilibrium gas-solid purification device, which completely avoids the influence of carbon dioxide and water vapor on the concentration of the neutralization liquid, and avoids accidents where high concentration caustic potassium or caustic soda purification solutions are mistakenly used as titration standard solutions. During the work process, users do not need to touch organic solvents with their hands, reducing the harm of chemicals to the human body.
