Water Soluble Acid & Base Tester

Summary
The instrument is designed and made as per the National Standard of People's Republic of China GB/T259 "Test Methods for Water Soluble Acid & Base of Petroleum Products". It is suitable to determine the water soluble acid & alkali in the liquid petroleum products, additives, lubricant greases, paraffin and waxy components as per GB/T259.
The instrument 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 using acidity meter to ascertain whether there exists the soluble acid and alkali in the extracted solvent.
