CO2 analyzer measures absorption by carbon dioxide of appropriate wavelengths of infrared light. Infrared light is passed through a cell containing the gas to be measured and the amount of light transmitted is compared with a reference value. It uses a high-grade light source with a quality detector to provide accurate measurement of carbon dioxide. It can detect gross amount of carbon dioxide in a breathing medium.

Fire suppression systems must be put in place to protect servers and other equipment. When choosing a fire suppression system, it is important to choose one that will put out a fire, but not destroy the equipment in the process. A popular method of fire suppression, as carbon dioxide reduces the oxygen content to the point where the atmosphere can no longer support combustion. This system attacks all the three necessary elements for a fire to occur. CO2 will displace oxygen so that the amount of oxygen remaining is insufficient to sustain the fire. It also provides some cooling in the fire zone and will also reduce the concentration of gasified fuel.

CO2 Incubators use steam-generators or atomizers to control relative humidity levels but most small to mid-sized incubators use humidity pans to produce humidity through evaporation. CO2 incubator is an apparatus used to grow and maintain cell cultures. It keeps cultures at an optimal temperature and humidity. It also regulates the carbon dioxide and oxygen content of the atmosphere inside. It is often used in laboratories to maintain specialized carbon dioxide levels for different organisms.
