GD-251 Petroleum Products Total Base Number TBN Tester

Purpose:

GD-251 Petroleum Products Total Base Number Tester 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 ZD-2 Automatic Potential Titrimeter and DZ-1 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.
