Automatic acid value tester is based on GB / T 7304 Petroleum products and lubricants – Determination of acid method (potentiometric titration), determination of GB / T 18609 crude acid number (potentiometric titration) and other standards designed by the instrument by potentiometric titration automatically determine the titration end point and automatically calculate the results. The instrument is suitable for the petrochemical industry measurement of crude oil, petroleum products, lubricants and other samples in acid value, determination of the acid is one of the important indicators to determine the quality of the oil. Titration system uses corrosion-resistant materials processing, instrument measurement accuracy, long service life.
