化工工艺过程pH测量仪器的选型

Selection of process pH measurement instrument for chemical engineering

介绍了化工工艺过程ｐＨ测量用仪器的选型原则。首先应了解被测溶液的各种参数，同时应熟悉各种工业ｐＨ计的型号、性能与类别。对选型中应注的一些细节问题也作了深入的说明。

The basic principles for selection of chemical engineering process pH measurement instrument are decribed . Varions parame ters of test solution and the types, performances and models of the industrial pH instruments must be known clearly. The details for selection that should be taken into consideration are discussed.
