Carbon dioxide
Where is it found?
CO2 is a result of normal cell function when it is breathed out of
the body. Besides, it is an essential element in photosynthesis,
the process by which plants make food and energy. Levels of
atmospheric CO2 have increased since the Industrial Revolution. The primary causes are deforestation and the burning of
fossil fuels such as coal, for electricity, heat production and
for transportation (cars, ships, planes, etc.). It could also be
formed, as a secondary pollutant, by CO oxidation.
Why is it harmful?
Carbon dioxide (CO2) is the fourth most abundant gas in the Earth’s atmosphere being the main Greenhouse gas. It is an odourless, colourless, and non-toxic gas although its emission is an
environmental global problem, being the main gas pollutant contributing to the climate change. Besides, it is a contributor of the
acid rain, oceans acidifi cation and could displace oxygen (O2)
and nitrogen (N2). CO2 is removed from the atmosphere when it
is absorbed by plants and algae as part of the biological carbon
cycle.
CO2 cartridge
The Carbon Dioxide Cartridge has a built-in non-dispersive infrared sensor (NDIR) ideal to measure from low to high concentrations that can be found in the atmosphere. Besides, it includes
an automatic baseline calibration to maintain the long-term stability with no effect of humidity,
temperature and pressure, which are corrected in the algorithm.
