Product Description
I. Summary
 HZDS211 potentiometric titration automatic pH value meter is based on GB/T 7304-2000 Petroleum Products and Lubricants Acid Value Determination Method (Potentiometric Titration Method) equivalent to ASTMD664, SH/T0251-2004 and other standards to set the acid value of petroleum products and lubricants It is designed according to standards such as base value determination method (color indicator method) and GB/T 18609, SH/T0688, NB/SH/0836 determination of crude oil acid value (potentiometric titration method) and other standards
The instrument adopts the potentiometric titration method to automatically judge the titration end point and calculate the result automatically. The instrument is suitable for the determination of acid value in crude oil, petroleum products, lubricants and other samples 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 adopts imported original parts, which are processed by corrosion-resistant materials, and the measurement results of the instrument are accurate and the service life is long.
