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.
