Maximum Operating Depth Calculator

This calculator determines the maximum operating depth (MOD) at the provided partial pressure of oxygen (PO2) in bar with various fractions of oxygen (FO2). In technical diving, the maximum operating depth of a breathing gas is the depth at which the partial pressure of oxygen (PO2) of the gas mix exceeds a safe limit.

FO2 (ie: .21 = 21%):    
PO2 (1.2 to 1.6 bar):
