Nitrox Tools web based

This web based application is optimized for use on the iPhone and iPod touch using the built in Mobile Safari browser. Designed specifically for certified Enriched Air Nitrox Gas Blenders, the Nitrox Blending Tools allow for blending calculations to be made while at the fill station using your iPhone or iPod touch.

This application was developed to enable easy calculations of the basic formulas for Nitrox blending by topping up an existing mix (or an empty tank) and bleeding down an existing cylinder and topping with air or an available mix to make a lower percentage mix. Simple calculators are also provided to calculate Equivalent Air Depth (EAD), Maximum Depth for various partial pressures of oxygen and the “Best Mix” for a given planned depth and oxygen partial pressure.

Calculations are available in both Metric and Imperial/US systems of measure. Simply tap the button in the upper right corner of the screen to switch between the two systems. The button will be labeled “Metric” when you are using the Imperial/US system and “Imp/US” when you are using the Metric system.

This application is provided for you to use free of charge. However, this application is not a substitute for proper training and should not be used as a substitute for proper dive planning or the primary Nitrox blending calculation methods taught during training. Please do not attempt to handle high pressure oxygen or fill SCUBA cylinders without proper training. Training for Nitrox blending is available from various SCUBA Diving training agencies including PADI, SSI, TDI, NAUI and others.
