Nitrox Tools vs Nitrox Helper

Enriched Air Nitrox blending and planning tools in your hand and available at a touch. You can use these tools at your air station to provide the information you need to fill a Nitrox tank from any existing mix (or empty). Dive Planning tools provide your Equivalent Air Depth, PPO2 at your planned depth, Maximum & Contingency Operating Depth at various oxygen partial pressures and the "best mix" for a planned depth and oxygen partial pressure. You can easily switch between Metric and Imperial/U.S. systems of measurement to adapt to a new fill station. The dive planning tools also support both salt and fresh water calculations. Chances are you regularly work with a specific set of mixes and and common dive situations. Nitrox Tools includes the convenience of saved settings that you can recall at a touch and adjust to a new situation as needed. You can also select mix values using pre-installed default mixes or your own saved custom mixes. When updating one of the mixes for a tool you are offered a list of saved mixes that you can use directly or adjust as needed. You can save the currently displayed mix by clicking the "+" button. Just like with the saved calculations, you can re-arrange or delete any mixes in your saved list. Do you need to share your planning or blending calculations with other divers? All the tools have the ability to share the results of the calculations from within the application. You can set default email addresses and a subject within Nitrox Tool's settings that will be automatically added when you share a result. Nitrox Tools supports a number of blending methods: • Top Up - blend a final mix from starting mix and pressure using 100% oxygen and air or any available topping mix. • Bleed Down - save expensive oxygen and valuable time by easily calculating how much gas to bleed from an existing cylinder to switch to a different mix using air or any available topping mix. • Mix + Mix - make a specific final mix using the remaining gas in the cylinder and mixing that with banked Nitrox (rather than pure oxygen) and air or another topping mix. This enables the blending of Nitrox without the use of pure oxygen for certain combinations of mixes. Avoiding pure oxygen may increase the safety of the blending process and help manage the cost. • Top Off - determine the expected result from topping an existing cylinder with air or some other topping mix. This situation is common when a diver wants to have the blender top the mix remaining from the first dive with air from the boat's compressor. Remember you must always personally analyze your mix before diving it. 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 and planning methods taught during training. Please do not attempt to handle high pressure oxygen or fill SCUBA cylinders without proper training.

Nitrox Helper is a Nitrox calculator designed for qualified EAN divers. Whether you're at the dive shop deciding on your mix or reviewing calculations before a dive, Nitrox Helper gives you quick, accurate answers with an interface designed for ease of use - even with cold hands. Your essential dive buddy for Enriched Air Nitrox (EAN) calculations. FOUR POWERFUL CALCULATORS Best EAN Mix Calculate the optimal oxygen percentage for your planned depth and PPO limit. Know exactly what mix to ask for at the fill station. Maximum Operating Depth (MOD) Determine the deepest safe depth for any Nitrox mix. Essential for dive planning and safety. Equivalent Air Depth (EAD) Convert your Nitrox dive to an equivalent air depth for use with standard Recreational Dive Planner (RDP) tables. Oxygen Partial Pressure (PPO) Monitor your oxygen partial pressure at any depth. Clear safety indicators warn you when approaching or exceeding safe limits. SALT WATER & FRESH WATER Calculate accurately for both environments. Sea water (10.0 m/atm) and fresh water (10.3 m/atm) use different pressure factors - Nitrox Helper accounts for this automatically. A read-only indicator on every calculator tab shows your current water type so you always know what you're calculating for. 8 LANGUAGES Use the app in your preferred language: English (UK), English (US), Afrikaans, Greek, French, Spanish, German, and Dutch. PERSONALISE YOUR EXPERIENCE - 16 beautiful colour themes - Metric (metres) or Imperial (feet) units - Configurable decimal places (0-3) for depth and PPO results - Per-tab unit switching from the toolbar DESIGNED FOR SAFETY - Clear PPO safety status indicators (Safe / Caution / Danger) - Visual warnings when exceeding Maximum Operating Depth - Read-only water type indicator prevents accidental changes - Important safety disclaimer on every calculator PRIVACY FIRST Your data stays on your device.
