Calculate Nitrox mix


This tool is for convenience. It is provided as is and may be faulty. It does not replace measuring of the oxygen content of the bottle!

Use this at your own risk!


The form below lets you calculate the expected mixture generated by filling a tank with known mixture with a known other mixture to a given end pressure. It only provides an approximation and you always have to measure the actual tank content after filling with an O2 analyzer!
