[PSUBS-MAILIST] FW: O2 and CO2 sensors

[Sean T. Stevenson via Personal_Submersibles]

Oxygen 18% to 23% volume, target < 21%
CO2 <= 0.5% volume, target 0 (but sensor range to 1% is desireable for scrubber breakthrough test)
relative humidity (where controlled) 30% - 70%
cabin temperature 14°C / 57.2°F to 30°C / 86°F (from other ABS references)
