I carried a CO2 meter on a flight recently, to use CO2 as a proxy for COVID risk. The levels were quite high for the whole flight--over 1000 pretty much the whole time iirc and worse on the tarmac.

How did you calibrate the meter for the changing temperature and pressure? Most CO2 meter designs are extremely sensitive to pressure changes.

  It's a cheap portable, with no calibration possible. I have no idea what effect pressure would have on it, unfortunately.
