Product Description
Application:
This petroleum oil total base number tester is suitable to determine the base number of petroleum products and additives. It is designed and made as per the industry standard of petrochemical SH/T0251-93 Test Methods for Base Number of Petroleum Products. Also It conforms to ASTM D2896. It determines and calculates base number of sample based on acid-alkali neutralization principle, perchloric acid potentiometric titration methods, and potential changes to detect end point.
