Base Number Tester  
 
 
Base Number Tester is an automatic, portable titrator having control accuracy equivalent to just 0.02 mL. It makes use of Acid-
Alkali neutralization principle. Suitable to function in low as well as moderate working temperatures. Incorporated with dual end 
point detection methods based on pH and conductivity measurement. Our product is designed as per the Industry Standard of 
Petrochemicals ASTM D2896 and ASTM D4739 and is used to determine the base number of petroleum products and additives 
such as lubricants.
