This doesn't measure CO2 levels. It measures volatile organic compounds and calculates the amount of CO2 that would cause the same greenhouse effect.

Not even that. It is designed for hvac applications and measures VOCs on the assumption that they are from human breath and have a corresponding increase in CO2 levels due to breath.
