FDR-2201 Water-soluble acid and base number tester of petroleum products Scope This instrument was designed and manufactured in line with the standard GB/T259-88. It can measure liquid petroleum products, additives, grease, paraffin wax and waxy component water-soluble acid number or water-soluble base number. First, water soluble acid or alkali in the sample was extracted with distilled water or ethanol water solution, and then the extract was determined by pH indicator or indicator. Features 1, the instrument consists of two parts, the structure is simple, fully meet the requirements of the GB/T 259 standard. 2, the instrument adopts the independent control of the heating furnace, heating power continuously adjustable, heating control is extremely convenient. 3, the heating furnace using the glass fiber woven heating plate, it has the advantage of high heating efficiency, low energy consumption, no flame, etc.. 4, the test is convenient, the operation is simple, the measurement result is accurate.
