Indoor Air Quality Monitoring: How To Test, Measure ...

· In addition to getting the “big picture” of your indoor air quality, an indoor air quality monitor can be set up to provide threshold alerts. If, for example, the outside air has a CO2 level of 400 ppm, you could set up your monitoring equipment to alert you when indoor levels reach 950, and when the air has reached critical point at 1100 ppm.
