1、前言1979年研制了煤矿井下用定电位电解式一氧化碳浓度测定仪,国内各煤矿均积极引入,现已有200台以上的定电位电解式一氧化碳测定仪在使用。井下用的定电位电解式一氧化碳测定仪与过去使用的非分散式红外线一氧化碳测定仪相比,除重量轻、易于操作外,而且有价格便宜、精度和稳定性高等特点,因此,它适合于在测定地点经常移动,特別是在范围很广的井下使用。估计今后其使用台数还会增加。为了对能造成煤矿井下重大灾害的自然发火和井下火灾进行检测,煤矿就以此一氧 1, Preface In 1979, a constant potential electrolytic carbon monoxide concentration detector for underground coal mine was developed. All domestic coal mines are actively introduced. Now more than 200 fixed-potential electrolytic carbon monoxide detectors are in use. Compared with the non-dispersive infrared carbon monoxide detector used in the past, the constant potential electrolytic carbon monoxide detector used in the well is characterized by light weight, easy operation, low price, high precision and high stability, and therefore, it is suitable for use in The site of measurement often moves, especially in a wide range of downhole applications. It is estimated that the number of its use will increase in the future. In order to detect natural fires and downhole fires that can cause major disasters in coal mines, coal mines use the same oxygen
