Identifying poorly ventilated areas and using CO2 monitors

CO2 measurements should be used as a broad guide to ventilation within a space rather than treating them as ’safe thresholds’. Outdoor levels are around 400ppm and indoors a consistent CO2 value less than 800ppm is likely to indicate that a space is well ventilated. An average of 1500ppm CO2 concentration over the occupied period in a space is an indicator of poor ventilation. You should ...

CO₂ measuring instruments – TFA Dostmann

A CO 2 meter, also called a CO 2 traffic light, CO 2 detector or CO 2 alarm, measures the concentration of carbon dioxide in the indoor air. The device determines the levels of CO 2 in the room, given in ppm (parts per million). CO 2 meters show you visually and/or acoustically when the CO 2 concentration is very high that you must ventilate the room.. Most people spend a lot of time indoors.
