JDD5-WSZY-2008 microcomputer acid value analyzer is designed according to GB / T 7304 petroleum product and lubricant acid value determination method (potential titration method), GB / T 18609 crude oil acid value determination (potential titration method) and other standards The instrument uses potentiometric titration to automatically determine the end point of the titration and automatically calculate the result. The instrument is suitable for the determination of acid value in various samples of crude oil, petroleum products, lubricants, etc. in the petrochemical industry. The determination of acid value is one of the important indicators for judging the quality of oil products. The titration system is made of corrosion-resistant materials, with accurate measurement results and long service life.
