酸度计又称PH计,是专为测定水溶液中酸度(PH值)的分析仪器,它操作简单、使用方便、稳定性好、结果准确。因此,在化工生产、电镀工业,土壤普查、食品扦验、环境监测、医疗卫生、科学研究等部门都普遍应用,是分析实验室不可缺少的仪器之一。但如果使用不当,得到的分析结果就会失真,由此对生产、科研将会带来不应有的损失,所以熟悉、掌握酸度计的使用和维护,无论对生产或科研都是非常重要的。酸度计的品种和型号很多,性能也各有差异, Acidity, also known as PH meter, is designed for the determination of acidity (PH value) in aqueous solution of the analytical instrument, it is simple, easy to use, good stability, accurate results. Therefore, it is widely used in chemical production, electroplating industry, soil census, foodstuff inspection, environmental monitoring, medical treatment and sanitation, scientific research and other departments. It is one of indispensable instruments in analytical laboratories. However, if used improperly, the analysis results will be distorted, which will produce undue losses on production and scientific research. Therefore, it is very important for us to be familiar with the use and maintenance of acid meters, both for production and scientific research . Acidity meter varieties and models are many, the performance is also different,
