CO2 ppm - what does it mean?

ppm stands for parts per million

On our mini CO2 monitors the number tells us how many parts of carbon dioxide there are in one million parts of air.

For example if the carbon dioxide is at 546 parts per million (or ppm), that means in one million particles of air there are 546 particles of carbon dioxide.

CO2 ppm - what does it mean?

ppm stands for parts per million. This number tells how many parts of carbon dioxide there are in one million parts of air. For example if the carbon dioxide is at 546 parts per million (or ppm), that means in one million particles of air there are 546 particles of carbon dioxide.

OSHA (Occupational Safety and Health Administration) has established a Permissible Exposure Limit for CO2 of 5,000 ppm averaged over an 8-hour work day.

Green is 450 - 800

Blue - CO2 below 800ppm 

Yellow - CO2 800 to 1000ppm 

Orange - CO2 1000 to 1500ppm (a double beep will alarm at 1000 and 1200ppm) 

Red - CO2 greater than 1500ppm (a continuing beep will alarm)

Any alarms have a high chance of getting covid.
