Maximum Operating Depth (MOD)

These calculators are provided as a quick reference, if you are not trained in the use of these gases please seek training and validate the answer before diving the mix.

This ONLY calculates in the range of recreation diving 21% to 40% with a partial pressure of 1.4 ATA

The formulas are provided and can be validated in any physics course books.
MOD = (PP02 / F02) * (33*100) - 33
