Developing solution pH electrode: The pH electrode is made of low impedance glass sensitive film and can be used for pH measurement under various conditions. It has the characteristics of fast response and good thermal stability; Has good reproducibility, is not easily hydrolyzed, and basically eliminates alkali errors; The reference system composed of Ag/Agcl and gel electrolyte salt bridge has stable half cell potential and excellent anti pollution performance. The double hole ceramic diaphragm is not easy to block, has strong anti pollution performance, and is easy to clean. It can be directly used with various PH meters at home and abroad
