SH108C potentiometric Titration automatic Acid value Analyzer is designed and made as  GB/T 7304-2000 determination of Acid value of Petroleum products and Lubricants (potentiometric Titration) GB/T 4945-2002 determination of acid and base value of petroleum products and lubricants (color indicator method) and determination of acid value of GB/T 18609 crude oil (potentiometric titration),equivalent to ASTMD664. The potentiometric titration method is used to automatically discriminate the titration end point and calculate the results automatically. The 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 indexes to judge the quality of oil. The titration system is made of corrosion-resistant material. The measuring results are accurate and the service life is long.

Main features:

1. General computer and operating system, special software Chinese window interface, mouse, keyboard operation, man-machine dialogue easy to understand.

2. Real time display potential curve (E-V), first order derivative curve (dE/dV) and electrode potential (E), titration volume (V), titration result the whole process titration data browse, the powerful data processing function, Facilitate the reprocessing of the results; Titration results, data, curve mass storage, titration process data can be stored as Excel documents, easy to query

3. automatic printing curve, results and titration data dynamic when the (DET), equal amount.

4. The automatic "end point" discrimination of preset (MET), potentiometric titration of (MET), the effective filtering of false "end point" automatic cleaning, automatic rehydration, and automatic adding technical parameters of fixed value are as follows:
