The method uses alcohol to extract acid constituents from sample, and then uses alkali solution for acid titration.

Purpose and scope

The instrument is designed and made as per GB/T264 Test Methods for Acid Value of Petroleum Products and GB/T258 Test Methods for Acidity of Gasoline, Kerosene and Diesel Oil. It is suitable to determine acidity of gasoline, kerosene and diesel oil without any ethyl liquids, and the acid value of petroleum products. The test methods are as follows: use ethanol to extract acid component in the sample and then use alkali liquids to titrate it.

The instrument is also suitable to determine acid value of transformer oil and turbine oil as per GB/T7599 Test Methods for Acid Value of Transformer Oil, Turbine Oil on Process in the National Standard of People Republic of China.
