1.Overview: Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents. The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment. 2. Technical index: 1.Test range: 0.002～1mg KOH/g 2.Test error: ≤±0.005mg KOH/g 3.Repeatability: ≤0.005mg KOH/g 4.Ambient temperature: 10℃～45℃ 5.Relative humidity(RH): ≤85%RH 6.Voltage supply: AC220V/50Hz 7.Power: 50W Transformer oil acid value tester Advantage: Convenient and efficient, customers can calibrate the instrument and neutralization solution at any time, so that the instrument can overcome the defects of the concentration of neutralization solution during use. Features: 1. The transformer oil acid value tester adopts the principle of titration neutralization method. Under the control of the microcomputer, the end point judgment of liquid injection, titration, stirring, neutralization and titration is automatically completed. The LCD screen displays the measurement results and automatically prints the measurement results. The measurement process only takes 7 minutes. 2. Use the special reagent bottle to hold the extraction liquid and the neutralization liquid. The reagent is isolated from the air during use to avoid the influence of volatilization and carbon dioxide in the atmosphere. At the same time, it also protects the operator. 3. The LCD screen displays and the Chinese menu guides the operation. The operator only needs to input and confirm the relevant parameters, and the instrument can automatically measure the acid value of the sample. Precautions: 1.The peristaltic pump hose is easy to wear. Please check carefully whether the hose is damaged or stuck to reduce the impact on the instrument. 2.When preparing the extract, the container must be dry and free of water. Keep the extract sealed 3.It must be cleaned up after the test.
