The oil product acid-base value tester adopts the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, it finds the equivalence point and the corresponding volume of the standard titration solution, thereby calculating the acid-base value in the sample. This instrument is applicable to relevant regulations and can accurately detect the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel oil, and gasoline.

Technical Features of Oil Acid-Base Value Tester

The oil acid-base value tester adopts the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, it finds the equivalence point and the corresponding volume of the standard titration solution, thereby calculating the acid-base value in the sample. This instrument complies with relevant regulations and can accurately detect the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel oil, and gasoline. It is widely used in chemical, electric power, petroleum and other industries, and is an ideal replacement product for current petroleum product acid value testers.
