can anyone tell me how to sync this app to my AMBIT2. thanks
In the test it only works up to 5000 meters. My question is if it works at higher altitudes?
I'm afraid not. I have tested it in himalaya and it works only up to 5000m. It's because the alti value is programmatically limited by suunto.
This may not be accurate everywhere, even if you use barometric pressure. The latitude of your location has a lot to do with the equation since the atmosphere is thinner as you go further South or further North toward the poles. This is a significant change in places like Alaska, USA. Further, since the Suunto does not show true barometric pressure, but adjusted pressure, a calculation using pressure won't be accurate either.
% of O2 in Air is about 21% at Sea Level. Should the figure shown be a true reflect of this and decreasing as we ascend, i.e. e.g. @3374m, approximate % of O2 in Air decreases to 13.8%?
Proportion of O2 remain the same with altitude at about 21%. It's the density/pressure which decrease meaning there is less molecules of air. So at 0m you have 100% of the molecules and higher you get, that % decrease.
Love the application! But I always looked a pressure.
Isn't the %O2 proportional to the absolute pressure? So that O2% = SUUNTO_PRESSURE /1013*100? Or did I miss something?
Of course you are right. Pressure measurement is programmatically limited, so I tried to go out of the boundaries using altitude. It didn't work because altitude is deviated from pressure :-)
