文中主要介绍了加伐尼电池法和检定管法两种检测器的检测原理、结构特征、影响因素(压力、干扰气体),在具体仪表方面,介绍了 OM—4C 型加伐尼电池式氧气浓度计(便携式)的结构、规格及使用条件等。在检定管法中介绍了Ⅰ型和Ⅱ型两利种氧气检定管。在二氧化碳检测部分介绍了19型、S7型和 S8型三种光干涉式检定器,此外还介绍了检定管式的二氧化碳检定器及 A、B 两种二氧化碳检定管的结构,使用条件等。
In this paper, the detection principle, structural characteristics and influencing factors (pressure, interference gas) of two kinds of detectors, such as battery method and test tube method, are introduced. In terms of specific instrumentation, OM- Concentration meter (portable) structure, specifications and conditions of use. Introduced in the test tube method type Ⅰ and Ⅱ two kinds of species of oxygen test tube. Introduced in the carbon dioxide detection section 19, S7 and S8 three kinds of optical interference detector, also introduced the verification of carbon dioxide detector and A, B two carbon dioxide test tube structure, conditions of use and so on.
