It is suitable to determine water soluble acid and alkali in the liquid petroleum products, additive, lubricating grease, wax, and waxy products.

The instrument use distillated water or alcohol extract water soluble acid and alkali. Then use methyl orange or phenolphthalein indicator to check color of extracted liquids, or use an acidometer to determine pH of extracted liquids, so as to detect whether there is water soluble acid and alkali exist.
