WHAT IS A CARBON DIOXIDE MONITOR?
CO2 Monitors measure the level of carbon dioxide (CO2) in an area to give an indication of how well ventilated it is. Knowing the CO2 level can help you identify if you need to take steps to improve ventilation or remove pollutants in your space. Good air quality can help lower the risk of airborne infections as well as support our general well-being. Poor ventilation has been shown to cause symptoms such as tiredness and headaches.
**Please note: These devices are not carbon monoxide detectors and are not life safety devices.

TIPS FOR ACCURATE READINGS
Take the device outdoors in an open area away from crowds. After a few minutes, the reading should be between 400 to 450 ppm. This means it is properly calibrated. If the device is not properly calibrated, follow the instructions in the user manual. Always take readings at least two meters away from people’s faces or your readings may be artificially high.
Readings should be performed when the space is occupied. If you expect 30 people in the room, you’ll want to take a reading with 30 people present.
You may notice the readings stay steady, rise continuously or cycle from higher to lower values. These patterns provide hints to how the space is ventilated and may guide your troubleshooting to improve ventilation in the space.
