    What would be a relatively simple methodology to measure the CO2 concentrations of the air? Any help is appreciated. Thanks!

    The simplest way would be with a CO2 meter: http://www.vaisala.com/instruments/products/carbondioxide/gm70 [Broken]

    Thanks! As a side note, would it be possible, knowing the volume of a room, to create a chemical reaction allowing an individual to calculate the CO2 concentration from the mass of the product?

    Yes, you could have a known concentration of CaOH2, blow a known volume of air through it and either titrate the remaining CaOH2 or filter out the CaCO3 and weigh it

    For the record: Ca(OH)2.
