CO2 Data Loggers

Why Monitor CO2 levels?
There are legal limits to the level of carbon dioxide that you can expose people to.

A high level of carbon dioxide in a room indicates inadequate ventilation. This can cause
headaches, fatigue, eye and throat irritation, increased heart rate, dizziness,
fatigue, rapid breathing visual and hearing dysfunctions.

1000ppm should be used as an upper limit for all indoor areas.
Exposure to higher levels may cause unconsciousness or death within minutes of the exposure

600ppm     People notice the air is "stuffy."

1000ppm   Indicates inadequate ventilation. Complaints of fatigue, headaches ad eye/throat irritation will be widespread.
Should be upper limit for indoor areas.

10,000ppm  Some people may begin to feel; shortness of breath, difficulty in breathing,
rapid pulse rate, headaches, hearing loss, hyperventilation, sweating, and fatigue.
Can cause drowsiness with prolonged exposure.
