A:Brief description:
1.DSHD259 WaterSoluble Acid & Base Tester is designed according the national standard of People’s Republic of China
GB/T259 Test Method for Water Soluble Acid & Alkali of Petroleum Products.
2.DSHD259 WaterSoluble Acid & Base Tester is applied to determine the water soluble acid & alkali in the liquid petroleum products,
additives, lubricant greases, paraffin and waxy components as per GB/T259.
3.Its operation steps is to extracts the water soluble acid & alkali in the sample using distilled water or ethanol solution.
Then check color change of extracted solvent by methyl orange or phenolphthalein indicator respectively or
determine the pH value of extracted solvent by acidity meter to ascertain whether there exists the soluble acid and
alkali in the extracted solvent.
