What's CO2? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

Carbon dioxide (CO 2) is a molecule composed of one carbon atom and two oxygen atoms. It is colorless and odorless gas at room temperature. When the temperature drops below -78 °C at normal pressure, it becomes solid (this is called dry ice). CO 2 is one of the most important gases on earth and is used in a process called photosynthesis.
