二氧化碳是一種酸性氣體，因此可以跟鹼反應。例如二氧化碳跟氫氧化鈉反應：
A carbon dioxide sensor that steps CO2 concentration utilizing a nondispersive infrared sensor Lousy air flow is amongst the primary triggers of too much CO2 concentrations in closed Areas, resulting in lousy indoor air high quality. Carbon dioxide differential previously mentioned outdoor concentrations at constant condition problems (in the event the occupancy and air flow program Procedure are sufficiently extended that CO2 concentration has stabilized) are sometimes utilized to estimate air flow costs for every human being.
Please Take note: You have to be 18 years of age or older to order and conform to all regulations governing the use and possession of airguns in your neighborhood space. More Information

在寒冷的冬天，我们关上门窗，形成一个封闭式的环境，阻挡室外寒冷空气的进入。随着我们吸一口空气中的氧气，呼出一口身体内产生的二氧化碳，房间内的氧气得不到补充，而二氧化碳浓度却越来越高。这个时候我们并不想开窗通风，因为一开窗，冷空气、雾霾和室外噪音就会进入室内。夏天我们因为常开空调，也不愿意开窗通风，这样室内的空气虽然变得凉爽，但完全没有新鲜空气进来，二氧化碳的浓度不断上升。结果，很多人在家里和办公室一直处于缺氧状态，时间长了对身体有很大的危害。
