SH108C Potentiometric titration automatic pH meter
The SH108C potentiometric titration automatic acid-base value meter is designed in accordance with GB/T 7304-2014 "Determination of Acid Value of Petroleum Products (Potentiometric Titration Method)" equivalent to ASTM D664, SH/T 0251-2004 "Determination of Alkali Value of Petroleum Products (Perchloric Acid Potentiometric Titration Method)", SH/T 0688 "Determination of Alkali Value of Petroleum Products and Lubricants (Potentiometric Titration Method)", NB/SH 0836 "Determination of Acid Value of Insulating Oil (Automatic Potentiometric Titration Method)", GB/T 18609 "Determination of Acid Value of Crude Oil (Potentiometric Titration Method)" and other standards
The instrument uses potentiometric titration to automatically distinguish the titration endpoint and calculate the results. This instrument is suitable for measuring the acid value in various samples such as crude oil, petroleum products, lubricants, etc. in the petrochemical industry. The determination of acid value is one of the important indicators for determining the quality of oil products. The titration system uses imported components, which are processed from corrosion-resistant materials. The instrument measures accurately and has a long service life.
