Provides divers with a verification mechanism when purchasing enriched oxygen cylinders. Oxygen nitrox analyzers may require calibration before use. Oxygen nitrox analyzers use electrochemical cells, which lessen in voltage output over time and must be replaced every years. What Is an Oxygen Nitrox Analyzer? Divers: Oxygen nitrox analyzers are used by divers and equipment technicians to verify oxygen concentrations within the tank. Dive Shops: These are used in dive shops for verification purposes at dive fill stations.

What Is Enriched Air Nitrox? An oxygen nitrox analyzer is made up of two main components: The electronics that consist of an on-board digital processor along with an analog to digital converter. The electrochemical oxygen sensor, a galvanic cell that outputs electrical energy.

This signal comes from the electron transfer in a redox reaction modulated by the detected oxygen. The partial pressure sensor outputs a voltage proportional to the oxygen concentration. The most in-depth article about oxygen sensors is by Mr.

Paul Raymeakers. In general, operation of an oxygen nitrox analyzer follows these steps: First, ensure the unit is calibrated to display Place the dome fitting directly onto the cylinder valve. Carefully turn ON the valve for about 10 seconds. To clearly identify them from air cylinders, tanks filled with EAN are marked with a yellow and green tank band at the top, just below the crown. The oxygen mix percentage is written on a label or tag, which is important because the percentage affects your depth limits and no stop dive time.

Enriched air has more oxygen than air does, which reduces the percentage of nitrogen. We all learned in our Open Water Diver course that, when you dive, the water pressure causes nitrogen from the air you're breathing to dissolve in your bloodstream and tissues. The higher the pressure deeper the dive and the more time under pressure bottom time , the more nitrogen dissolves in.

If you surface with too much dissolved nitrogen in your tissues, bubbles can form causing decompression sickness DCS. Staying within the no stop limits limits the theoretical amount of dissolved nitrogen so that you can ascend directly to the surface but make your safety stop.

If you exceed this limit as do tec and commercial divers , you have to make mandatory decompression stops in stages as you come up to keep the risk of DCS low. Based on the Recreational Dive Planner, for example, a diver on air at feet reaches his or her no-decompression after 20 minutes. At 60 feet, the diver's maximum time would be 55 minutes.

But, nitrox changes these numbers. Because you're breathing less nitrogen, less dissolves into your body, all else being equal, allowing a longer no-decompression limit. This can be calculated using an equivalent air depth EAD , which is a shallower depth at which nitrogen would be going into solution at the same rate if you were using air. If, for example, at feet with EANx32 has an EAD of 90 feet, so you're absorbing nitrogen as if you were 15 feet shallower.

Therefore, the diver's ordinary no-decompression limit of 15 minutes extends to 25 minutes — that's a 66 percent increase in bottom time. The best application of nitrox is in the to foot range.

No stop times for dives shallower than 50 feet are often so long that you'll empty your tank before you run out of dive time. Using EANx36 at 60 feet, your no stop limit is or more minutes depending on your computer for your first dive, so you'll again be limited by your gas supply, not your decompression limit.

You were taught to dive well within limits, and by pushing the limits outward, you can dive longer and still be conservative. Many enjoy nitrox diving to or even beyond air limits without being anywhere near the actual no stop max. As with air this doesn't guarantee percent safety, but staying well within limits reduces practical DCS risk for most divers. Interested in diving nitrox? This benefit does not come without some cost. Oxygen, while useful and essential to life, can become hazardous in high concentrations.

Too much oxygen at pressure affects the central nervous system — oxygen toxicity — causing convulsions or seizures, visual distortions, ringing ears, nausea, twitching, irritability and dizziness, with convulsions or seizures being the most serious while diving. Oxygen toxicity hits are very rare in diving, but if they happen under water, they happen without warning and lead to drowning if you lose the regulator while convulsing.

Any percentage of oxygen can cause toxicity if you go deep enough, but with air you have to go well beyond established depth limits for this to be likely. With nitrox, the depth limit is within recreational diving depths, and the more oxygen, the shallower the limit — the limit is the depth at which the PPO2 would be 1. Long term exposure to elevated oxygen can cause a different type of oxygen exposure as well.

Earning a nitrox certification is required because, among other issues, EANx divers must learn now to manage their oxygen exposure. When enriched air first came into recreational diving, there were no EANx dive computers and few tables. So, you figured out everything with a pencil and calculator. Then stop by a Force-E Scuba Center and talk to one of our highly trained instructors.

This course is completed in one day, in about hours with a Force-E Instructor. Note there are no dives required for this certification, only a classroom session.

You can choose to do your academics online or book version. If you choose the online academics you do all your reading, videos and test online on your time. If you choose the book, you will do your reading and knowledge questions at home then join us for a classroom session to watch a video and complete the final exam. After your classroom session with your instructor and you've completed your certification you will probably be excited to jump in the water and dive with Enriched Air Nitrox.

Our instructors can help you set up a dive trip through our store.
