枪式酸度计体积很小,重量很轻,便于携带至工厂的车间或野外现场进行pH值测定。这种pH计的电极是具有穿刺力的微型复合pH电极,可以插入半固体、胶冻等物体内部测定其pH值。仪器在使用中不须调零,使用和维修均甚方便。复合电极的锑头在使用前用全相砂纸打光后,放在蒸馏水中浸泡几分钟,即可进行测定。电极响应快,重现性好,但不适用于含有氧化剂和含有羟基羧酸盐的溶液。

The gun acidimeter is small in size and light in weight, making it easy to carry to the factory floor or field for pH measurements. The electrode of this pH meter is a punctured micro composite pH electrode, which can be inserted into the semi-solid, jelly and other objects within the measured pH value. Instrument in use without zero, use and maintenance are very convenient. The antimony head of the composite electrode is polished with all-purpose sandpaper before use and then immersed in distilled water for a few minutes to be measured. Electrode response fast, reproducible, but does not apply to contain oxidants and hydroxycarboxylate-containing solution.
