Petroleum Products Acid Number Tester

This instrument is in accordance with the Standard GB/T 7304 Of petroleum Products and Lubricants Acid Value Determination (Potential Titration Method), GB/T 18609 "Determination of Crude Oil Acid Value Potential Titration Method", industry standard NB/SH/T 0836 The determination of the value of insulation oleic acid automatic potential titration method and other relevant standards designed and manufactured, it is suitable for detecting the acid value of transformer oil, turbine oil, anti-fuel, diesel, gasoline and other petroleum products. The acidity of petroleum products can also be determined according to GB / T 258. It can be widely used in chemical, power, petroleum and other industries, and is an ideal replacement product for the current petroleum product acid value tester.

This instrument is also suitable for the requirements of ASTM D664-2011 (testing acid value).
