"nitrox4divers" allows you to calculate quickly and safely the PPO2 (partial pressure of oxygen) at a given depth.You can calculate your BEST MIX!And finally, you may discover the MAX depth allowed at determined PPO2%% with an oxygen percentage that YOU HAVE CHOOSEN!NO LIMIT TO POSSIBLE COMBINATIONS.notes:The program was written under the supervision of an instructor PADI nbr. 980286*** If you liked the application or found it helpful even for a moment, help me to develop other application.
