多孔气体扩散电极法一氧化碳个体监测仪的研制

Carbon monoxide personal detector based on porous gas diffusive electrode

研制了用多孔气体扩散电极的电化学传感器和大规模低功耗ＩＣ器件组成的一氧化碳个体监测仪器。检测浓度范围为０～１００ｍｇ·ｍ－３，便于个体携带。与相适配的支持部件相连接，可组成无人值守自动监测系统。该仪器具有直读瞬时浓度和时间加权平均浓度，剂量值读出以及８ｈ以上的数据记忆与再读出等功能。

CO personal detector bascd on porous gas diffusive electrode has been developed. Accurate readings are obtained over the range of 0～100mg/m3CO. An auto-monitoring system can be formed when it is connected to the supporting equipment. The instant concentration, time-weighted average concentratioon and dosage of CO can be obtained and data of 8 hours can be stored in the instrument.
