Calculator

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!

Current tank content

Current tank pressure (bar)

Current oxygen content (%)

Filling information

Final pressure (bar)

Filling oxygen content (%)

Resulting mix

Oxygen content	MOD (ppO₂=1.4)

Equivalent Air Depth
