一、一氧化碳的性质一氧化碳(CO)是无色、无臭的气体,比空气轻.当它的浓度超过35PPM 时就有毒性.在通风不足的燃烧中CO的浓度会增加.在工业环境中,CO首先是可燃性气体,会发生燃烧和爆炸;在民用建筑中CO会预示加热装置的故障.这一切可以说明CO探测的重要性.二、一氧化碳的探测种类CO的探测有五种实用技术,可以根据所需的性能和成本进行选择,这些技术是:比色式、半导体式、电化学式、薄基型、光学吸收式.通常以电池为电源的比色式和以市电为电源的半导体式传感器占民用市场的主导地位,工业方面 First, the nature of carbon monoxide Carbon monoxide (CO) is a colorless, odorless gas, lighter than air. When its concentration exceeds 35PPM when toxic .In under-ventilation combustion CO concentration will increase.In the industrial environment, CO is the first combustible gas, the occurrence of combustion and explosion; CO in civil buildings will indicate the failure of the heating device, which can explain the importance of CO detection. Second, the detection of carbon monoxide CO detection of five practical techniques, The choices are based on the performance and cost required: colorimetric, semiconducting, electrochemical, thin-based, optically absorptive, colorimetric and battery-powered semiconductors Sensors occupy the dominance of the civilian market, industry
