mixtures that can be used for the gas check and calibration process. There are
three default mixtures:

Fresh Air – assumed values of fresh air are CH
4
0.0%, O
2
20.8, and all
other optional gasses 0ppm. CO

is not available to calibrate in air.

Note: The oxygen concentration is editable between 20.8% and 21.0% -
