室内有毒易爆气体的检测

随着城市生活水平的提高,室内装修装饰日益普及.各种新材料的引入,使得室内的各种有害气体总量日益增加.长期生活在这样的环境下,会对人体健康产生极为不利的影响.居民生活用煤气,在给人们生活带来便利的同时,作为一种可燃性、有毒气体,也具有极强的危害性.因此,研制一种能检测多种有害气体的实用仪器,具有很大的应用价值.本仪器为便携式多功能仪器,采用可充电电池供电,可以检测ppb的挥发性气体,显示气体浓度值,也可检测煤气,并具有声光报警功能.

Detection of Indoor Poisonous and Explosive Gases

With the enhancement of city living standards, home decoration has been more and more popular these years. Different kinds of material have come into people's home, which contribute a lot to the emission of poisonous gases. Living in such environment for a long time will eventually have a bad effect on one's health. In another aspect, the coal- gas in the house -hood for cooking is also explosive and poisonous. Therefore the research on indoor hazardous gases measurement and alarm device is of much economic and practical importance. The device is portable and versatile. We use rechargeable battery as power supply. The device can detect the density of gases at the ppb level for the emission of the material and the value can be shown on the display. It can also detect the percentage of LEL for coal gas, and make the sound and light of alarm.
