Ⅰ. Introduction

GD-259 Liquid Oil/Lube Grease/Wax Water Soluble Acid & Alkali Tester is designed and made as per GB/T 259 Test Methods for Water Soluble Acid and Alkali of Petroleum Products.

  GD-259 Liquid Oil/Lube Grease/Wax Water Soluble Acid & Alkali Tester  is suitable to determine water soluble acid and alkali in the liquid petroleum products, additive, lubricating grease, wax, and waxy products.

Ⅱ. Characteristics

The water soluble acid and alkali tester(for testing Liquid Oil/Lube Grease/Wax ) 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.
