A1041 Oil pH Tester meets the standard: GB/T264、GB7599-87、GB/T7304-2000、GB/T 18609-2001、D664—01、ASTM D664-2011。 A1041 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 the standard titration solution can be identified to determine the pH value of the sample. A1041 can accurately detect the pH value of petroleum products such as transformer oil, turbine oil, fire-resistant oil, diesel, gasoline, etc; Widely used in industries such as chemical, power, and petroleum, it is an ideal replacement product for the current acid value analyzer for petroleum products.
