The A1045 petroleum product acid value tester adopts the principle of potentiometric titration. By recording the electrode potential and titration volume during the titration process, the equivalent point and corresponding volume of standard titration solution are found to determine the acid value or base value in the sample. The instrument can accurately detect the acid value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel, gasoline, etc. Applied in industries such as chemical, power, petroleum, environmental protection, and railway.
