Scope of application
It is applies to determine the water soluble acid & alkali in the liquid petroleum products, additives, lubricant greases, paraffin and waxy components as per GB/T259.
What 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.
1, instrument consists of two parts, simple structure, in full compliance with GB / T 259 standards required.
2, independently controlled heating furnace, heating power continuously adjustable heat control is extremely convenient.
3, heating furnace using woven glass heating plate, with high heating efficiency, low energy consumption, no open flame characteristics.
4, easy to operate, accurate results.
