摘　　要：矿用测量CO的仪表普遍采用电化学敏感元件,该反应机理存在交叉干扰的特性,在救生舱内气体较为复杂的情况下测量数据存在极大误差。就电化学反应机理对救生舱内环境气体组成进行了详细的测试分析,提出了数据差异特征和抗交叉干扰方法。Electrochemical sensing element is wildly used in mine CO measuring instrument, and its reaction mechanism exhibits cross - reactivity in the refuge chamber, there is a great measurement error in complex gas circumstances. This paper analyzes the gas com- position in refuge chamber with electrochemical reaction, presents the characteristic of data differences and provides some methods of resistance cross interference.
