Carbon Dioxide (CO HVAC Basics - Honeywell

Carbon monoxide (CO) can be harmful, even at very low levels (25 to 50 ppm). CO2 as an IAQ Indicator Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air quality equation. Low CO 2 levels do not indicate good air quality while high CO2 levels do not mean that air is harmful. So CO2 sensors should be presented and sold ...
