CO2 Monitors

An Aranet4 Home Indoor Air Quality Monitor sits on a shelf. It shows a ‘safe’ reading of 775 ppm, as well as temperature and relative humidity readings.

Have you heard? Starting this month, you’ll be able to borrow a carbon dioxide (CO2) monitor from any of Nova Scotia’s nine public library regions.

What is a CO2 monitor?

CO2 monitors allow individuals to keep an eye on air quality. High readings may indicate that the ventilation around the monitor is not sufficient and that steps are needed to improve the air quality.

NOTE: The CO2 monitors are not carbon monoxide detectors and are not life safety devices.
