Ⅰ. Purpose:

GD-251 compressor oil Total Base Number analyzer TBN tester)  is designed and made as per the Industry Standard of Petrochemical SH/T0251-93 Test Methods for Base Number of Petroleum Products.  

  GD-251 compressor oil Total Base Number analyzer TBN tester) is suitable to determine the base number of petroleum products and additive.

This  compressor oil total base number tester 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.
