Features
Read full description

Gas Blender will help you to mix Nitrox and Trimix gasses for scuba diving. It works in both imperial and metric and can use both Ideal Gas Formulas as well as Van de Waals gas formulas. When planning your gasses you can also see the MODs based on Narcosis, Gas Density and Oxygen toxicity for bottom gas, deco gas and CCR (individually selectable). Gas Blender keeps the mixes you have planned so you can refer to them without having to enter the information again. You can choose to use the Ideal Gas Formula (what is normally taught) or the more accurate Van de Waals formula which will take some of the estimation out of the mixing process. This combined with the user selectable time to fill will help you to mix an accurate blend every time.
