There are CO2 scrubbers on board, the crew turns them on/off to control concentrations. It's one of the things I checked before I went on every watch as OOD (officer of the deck): the CO2/O2 concentrations. (One of our weapons officers was really sensitive to CO2 concentrations and would s*t all over any OOD who let them get too high.)
- solveit 4y agoI'm led to believe that the CO2 concentrations still routinely go above 2000 ppm though. Is that right?

- alliao 4y agothat is pretty darn cool, not sure how to convert that torr to ppm though, in they video they mentioned it's partial pressure? so sounds like one is able to work out percentages therefore ppm by the reading?
- crmd 4y agoTo convert a partial pressure in torr (mmHg) to ppm, you divide the partial pressure by the total atmospheric pressure (both in torr) and multiply by 1 million.
- dmitriid 4y agoIs there a "dad with a thermostat" joke in there somewhere, only applied to CO2? :)
