It is formed during breathing of humans and animals, in fermentation and decomposition processes and during the burning of fossil fuels. Plants need carbon dioxide in the assimilation process. It can therefore be used as a fertilizer to enhance plant growth.
Carbon dioxide is a good indicator for indoor air quality.
In large concentrations carbon dioxide is a potential safety hazard and it inhibits bacterial growth. Vaisala's carbon dioxide products are available for human and product environment control as well as for safety measurement. GMT220 Series Transmitters are designed to measure carbon dioxide in harsh and humid environments. The modules are optimized for integration into equipment for greenhouse control, incubators, fermentors, safety alarming and integrated systems.
