气体中微量氧的连续测量,一直是较难解决的课题。最近由南京化学工业公司研究院和泰兴自动化仪表厂共同研制的样机经省机械厅和省石化厅联合组织,通过了省级鉴定。该测量仪是应用传统的原电池的方法,在电解溶液中所进行的电极反应产生电势,因而具有很高的灵敏度,同时又根据亨利定律,在达 Continuous measurement of trace oxygen in the gas has been a difficult problem to be solved. Recently, the prototype developed jointly by Nanjing Chemical Industry Research Institute and Taixing Automation Dashboard Factory was jointly organized by Provincial Department of Machinery and Provincial Bureau of Petrochemical Industry and passed provincial appraisal. The instrument is the use of the traditional method of the original battery, the electrolysis solution carried out in the electrode reaction potential, which has a high sensitivity, but also according to Henry’s law, up to
