Introduction: The instrument is designed and manufactured in accordance with the requirements of the national standard GB / T 259 "Determination of water-soluble acid and alkali for petroleum products" and is suitable for the determination of water-soluble properties of liquid petroleum products, additives, greases, paraffin and wax components Acid or water-soluble base. The instrument uses distilled water or ethanol aqueous solution to extract the water-soluble acid or water-soluble base in the sample. Then, the change of the color of the extract is checked with methyl orange or phenolphthalein indicator, or the pH of the extract is measured with an acidity meter Value to determine the presence or absence of a water-soluble acid or a water-soluble base. Technical Parameters: 1, the working power: AC220V ± 10%; 50Hz. 2, heating power: 100W ~ 1000W continuously adjustable. 3, acidity meter: range 0 ~ 14.00pH, accuracy ± 0.01pH. 4, separatory funnel: 250ml. 5, measuring tube: 100 ml, 50 ml. 6, test tube: Φ18 mm × 100 mm. 7, conical flask: 100 ml. 8, ambient temperature: -10 ℃ ~ +35 ℃. 9, relative humidity: ≤ 85%. 10, the whole power consumption: not more than 1200W.
