ASTM D664 ASTM D2896 Auto Petroleum Product Total Acid and Base Value Tester TAN TBN Potentiom Titration Method
1. Product Introduction
GSSZ-V Alkalinity Automatic Titrator adopts the principle of potentiometric titration. Under computer control, it realizes automatic and visualized data processing of titration process. Different electrodes can be used for acid-base neutralization titration, precipitation titration, redox titration, complexation titration, non-aqueous titration (such as determination of mercaptan sulfur, acid (base) value in petrochemical oil products; acid value (acid value) in the food industry; acid value (acid value) in resins in the chemical industry) and other titrations; the instrument adopts imported titration unit to smooth the titration curve and correct the titration end point position to ensure the accuracy of the results. It is an essential instrument for petrochemical laboratories, analysis rooms and scientific research departments.
