Purpose:

GD-251 Total Base Number Meter is designed and made as per the Industry Standard of Petrochemical SH/T0251-93" Test Methods for Base Number of Petroleum Products" .

GD-251 Total Base Number Meter is composed of ZD-2 Automatic Potential Titrimeter and DZ-1 Titration Device.

GD-251 Total Base Number Meter 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.
