HSY-259 type petroleum product water-soluble acid and alkali tester Introduction
The water-soluble acid and alkali tester for HSY-259 petroleum products is designed and manufactured in accordance with the requirements stipulated by the People's Republic of China Standard GB/T 259 "Determination of Water-Soluble Acids and Alkali in Petroleum Products", and is applicable to GB/T 259. The specified method for the determination of liquid petroleum products, additives, greases, paraffin waxes and water-soluble acids and water-soluble bases of waxy components. The instrument extracts the water-soluble acid and the water-soluble alkali in the sample with distilled water or an aqueous solution of ethanol, and then checks the color change of the extract with methyl orange or phenolphthalein indicator, respectively, or determines the pH of the extract with a pH meter. Value to determine the presence or absence of a water soluble acid or a water soluble base. Features
