GD-251 Petroleum Products Base Number Tester
The instrument is designed and made as per the Industry Standard of Petrochemical SH/T0251-93 "Test Methods for Base Number of Petroleum Products". It is composed of ZD2 Automatic Potential Titrimeter and DZ1 Titration Device. It is suitable to determine base number of petroleum products and additive. 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.
