The BD-D664-A45 petroleum product acid value tester adopts the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, it can find the equivalence point and the volume of the corresponding standard titration solution, thereby determining the acid value or base value of the sample.
This instrument accurately detects the acid value of transformer oil, turbine oil, anti-fuel oil, diesel, gasoline, and other petroleum products. It is widely used in chemical, electric power, petroleum, environmental protection, and railway industries.
