摘要
目前PH酸度计广泛应用在化工、环保等领域,工业PH计作为一种常用的化学分析仪器,主要用来在线连续精确测量被测介质的酸碱度值。文章讲述了PH酸度计的定义、原理及测量方法。主要是针对目前煤直接液化备煤催化装置使用的PH计所遇到的实际问题及相应的改进措施进行介绍。
PH acidity is widely used in the chemical industry, environmental protection and other fields, chemical analysis of industrial PH meter as a common instrument, mainly used for online continuous measurement the measured p H value of medium. This article is about the definition of PH p H meter, principles, and methods of measurement. Is mainly aimed at the direct Coal Liquefaction coal catalytic equipment using a PH meter encountered practical problems and corresponding improvement measures were introduced.
