Lubricant Anti-Emulsification Tester High Accuracy PID Temperature Control Oil Water Separation Test Machine
The SH108C automatic potentiometric titration acid-base analyzer is engineered to comply with a full range of industry testing standards. These include GB/T 7304-2014 Determination of Acid Value of Petroleum Products (Potentiometric Titration Method) (equivalent to ASTM D664), SH/T 0251-2004, SH/T 0688, NB/SH/0836, and GB/T 18609, covering acid and base value testing for petroleum products, lubricants, insulating oil and crude oil.
Working on the potentiometric titration principle, the unit automatically detects titration endpoints and computes final results directly. It fits well for acid value testing across all kinds of petrochemical samples, from crude oil and refined petroleum products to lubricants — acid value remains a core benchmark for judging overall oil quality.
Its titration system is fitted with imported components made from corrosion-resistant materials, delivering stable, accurate test readings and a long service lifespan.
