About this app

Our Nitrox Virtual Analyzer is the first of its kind in the world. It gives you the ability to safely and conveniently learn how to operate a Nitrox Analyzer, used for scuba diving. Without having to visit a dive center to borrow and analyzer and cylinder of Nitrox or go to the expense of purchasing an analyzer & Nitrox cylinder. The app allows you to make mistakes in safety, and let the app guide you through the correct way to calibrate and analyze a Nitrox gas mix. The app has been written by experienced diving instructors, and closely resembles a real Nitrox Analyzer in both its look, operation, and response. So when you actually use a real Nitrox analyzer you will be familiar with its use. This app gives you the ONLY way to get certified by any diving agency for Nitrox without attending a class! A requirement for most Nitrox courses is to analyze a Nitrox mix, to obtain certification; if you haven't done that you should consult your instructor/dive center if you have correctly fulfilled the requirements of your course. NOTE: This app is for simulation purposes only, it CAN NOT actually measure the oxygen percentage in a gas. There is no Oxygen sensor in your mobile device!
