A Carbon Dioxide monitor measures the amount of CO2 in the air. CO2 concentrations change because of people breathing, cars running, combustion of hydrocarbons and many other sources. CO2 levels indoors can rise dramatically and affect cognitive function and performance. 

Remote CO2 Monitoring

You can monitor CO2 from anywhere in the world. Login to your Edge device or Cloud account wherever you are in the world and see the current CO2 levels as well as all the historical data.


Schools, Daycare, Universities and Colleges

High classroom CO2 levels in can significantly impair decision-making performance. This can have a detrimental effect in schools where large amounts of students, ventilation issues and other source elevate CO2 levels in classrooms and other areas. It has also been shown that high school CO2 levels can negatively affect student health and lower attendance rates.1

Berkeley Lab researchers found that even moderately elevated levels of indoor carbon dioxide
resulted in lower scores on six of nine scales of human decision making performance.

Commercial Offices

Monitor CO2 Levels and Ventilate appropriately to keep employees alert and productive. 

Employees are happier, more efficient and productive when environmental conditions are optimized. 

Greenhouses and Growers

Optimizing CO2 levels can help create better growing conditions, improve crop yields and growth rates.

At Home / Residential

Ensure the rooms in your home are being adequately ventilated, especially the bedrooms. If your room feels stuffy at night or you’re not sleeping well, monitoring could uncover the reason why. If you suffer from asthma, snoring or other issues, monitoring can help optimize your environment. 

Industrial / Manufacturing / Winemakers

CO2 is the by product of many industrial and manufacturing processes. CO2 is also produced during wine making and other fermentation processes.
