· Doesn''t really measure CO2, but responds to all kinds of other gasses too. Loses callibration. It''s mostly a chemical proces. The cool thing about the MHZ14 and the even better MHZ19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in the spectrum that CO2 absorbs in.
