Why Monitor CO2 in Classrooms?

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality ...

Inadequate Ventilation and High CO2 Levels

Inadequate ventilation can lead to the build-up of small amounts of contaminants which are difficult to identify and test, so carbon dioxide (CO2) levels are used as an indicator of adequate ventilation in a room. Carbon dioxide is released by combustion of fuels and every time we breathe. It is normally measured at 300-350 ppm (parts per million) in the atmosphere. The legal exposure limit is a
