The KR0251 automatic Automatic Potentiometric Titrator TAN/base value (BAN) measuring instrument is designed according to the standard SH/T0251-2004. The instrument uses the potentiometric titration method to automatically determine the end point of the titration and automatically calculate the result.
Potentiometric Titrator/TAN and TBN Tester/Petroleum Oil Testing Equipment
The KR251 automatic TAN/base value (BAN) measuring instrument is designed according to the standards of GB/T 7304-2000 petroleum products and lubricant acid value determination method (potentiometric titration method) equivalent ASTM D664, GB/T 4945-2002, SH/T0251-2004 and the determination of acid value of petroleum products and lubricants (color indicator method) and GB/T 18609 crude oil (potentiometric titration method). The instrument uses potentiometric titration method to titrate the acid value of petroleum products and lubricants. The fixed end point is judged automatically and the result is calculated automatically. This instrument is suitable for the determination of acid value in crude oil, petroleum products, lubricants and other samples in petrochemical industry. The determination of acid value is one of the important indicators to determine the quality of oil products. The titration system is made of imported original parts, which are processed from corrosion-resistant materials. The measuring results of the instrument are accurate and the service life is long.
