Oxygen analysis plays a vital role in scuba diving safety. By understanding and monitoring the oxygen content in scuba gas, divers can mitigate risks and enjoy their underwater adventures to the fullest.
Scuba Analyzer Oxygen Sensors
Oxygen analysis in scuba diving has evolved over the years, with advancements in technology enabling more accurate measurements. In the past, divers relied on chemical tests or hand-held analyzers, which had limitations in terms of accuracy and convenience. Today, modern scuba gas analyzers provide fast and reliable oxygen analysis, improving the overall safety of the sport.
Fast oxygen testing has been made possible by electrochemical sensor advances as shown below. These sensors have fast responses (less than 30 seconds) and can detect the full range of oxygen 0-100% with 0.1% resolution. Please note however, these cells are galvanic cells, and with time, they decrease their output voltage potential. This means they need regular calibration and after 2-3 years they must be replaced.
Nitrox Analysis for Scuba Tank Testing
Nitrox analysis is a critical process in scuba diving that involves analyzing the oxygen and nitrogen content in the breathing gas mixture. This analysis ensures that the gas mixture meets the desired specifications for safe diving.
A scuba gas analyzer, specifically designed for nitrox analysis, is used to measure the percentage of oxygen and nitrogen present in the gas. The results help divers determine if the nitrox mix is within the accepted limits.
The most common nitrox oxygen levels for recreational diving are 32% and 36%. These mixes have maximum operating depths (MODs) of 34 meters (112 feet) and 29 meters (95 feet) respectively, when limited to a maximum partial pressure of oxygen of 1.4 bar (140 kPa).
Nitrox mixes with higher oxygen levels are also available, but they are less common in recreational diving due to the increased risk of oxygen toxicity. For example, nitrox mixes with 40% oxygen or more are typically used by technical divers who are trained to manage the risks associated with high oxygen exposure.
Here is a table of some common nitrox mixes and their oxygen levels:
|Nitrox mix||Oxygen level||MOD|
|EAN32||32%||34 meters (112 feet)|
|EAN36||36%||29 meters (95 feet)|
|EAN40||40%||24 meters (79 feet)|
|EAN50||50%||18 meters (59 feet)|
If you are considering diving with nitrox, it is important to be properly trained and certified by a qualified scuba diving instructor.
|Benefits of Nitrox Analysis|
|1. Safety: Nitrox analysis ensures that the breathing gas mixture contains the desired oxygen percentage, reducing the risk of oxygen toxicity or nitrogen narcosis.|
|2. Extended Dive Time: By adjusting the oxygen content, nitrox mixtures allow for longer dives compared to regular air.|
|3. Decompression Requirements: Accurate nitrox analysis helps divers calculate the correct decompression requirements, reducing the risk of decompression sickness.|
When purchasing a Scuba Oxygen Analyzer, make sure the oxygen analyzer has a full 0-100% detection range. This is important since many oxygen detectors are used for personal safety protection and have a limited range 0-30%. Do not purchase these types. Make sure your oxygen analyzers can detect 0-100% volume.

Frequently Asked Questions
1. What is the best scuba analyzer?
There are several SCUBA oxygen analyzers that are credible. The most popular include:
- Analox Oxygen Analyzer 02EII Pro for Scuba Divers
- Analytical Palm 02 Analyzer
- Oxygen Analyzer O2BOX for Scuba by Forensics Detectors
- MaxtecO2+A Scuba Oxygen Analyzer
- Nuvair Pro O2 Oxygen Analyzer
2. What are the dangers of carbon monoxide (CO) contamination in scuba diving gas?
Carbon monoxide can be present in scuba diving gas due to various sources such as inefficient combustion of hydrocarbons, oil pyrolysis in air compressors, exhaust from engines, cracking of oil residue in diving cylinders, and other sources. Breathing gas contaminated with carbon monoxide can lead to carbon monoxide poisoning (COP), which can have serious health effects. Carbon monoxide binds to hemoglobin, reducing the ability of blood to carry oxygen and causing cellular hypoxia. Symptoms of carbon monoxide poisoning include weakness, nausea, vertigo, headache, blurred vision, loss of consciousness, and coma.
3. How can scuba divers protect themselves from carbon monoxide poisoning?
To protect themselves from carbon monoxide poisoning, scuba divers should engage in gas analysis to detect potential contamination. Strict standards have been issued regarding the limit of carbon monoxide in breathing gas, which should not exceed 5-10 ppm – however, ANY positive detection of carbon monoxide should be an alert, and would not be advisable to dive with even 1ppm of carbon monoxide in your tank. Proper compressor maintenance schedules, using high-quality equipment, and avoiding smoking near gas cylinders are important preventive measures. In case of carbon monoxide poisoning, immediate treatment involves administering generous doses of oxygen to displace carbon monoxide molecules from the blood, cells, and organs. Hyperbaric oxygen administration (HBO) can be used for accelerated CO displacement.
4. What is the purpose of using gas analyzers in scuba diving?
The purpose of using gas analyzers in scuba diving is to ensure the correct composition of breathing gases before a dive. Gas analyzers are used to determine the oxygen, nitrogen, and inert gas levels in various gas blends such as nitrox and trimix. They help identify potential contaminants such as carbon monoxide and verify the gas mix against the intended blend. Gas analyzers, such as the Analox range or the Divesoft and Analox gas analyzers, are reliable tools for monitoring and analyzing scuba diving gases.
5. Why is it necessary to label gas cylinders and ensure the maximum operating depth (MOD) is visible?
Labeling gas cylinders and ensuring the maximum operating depth (MOD) is clearly visible is important for scuba divers. Properly labeled gas cylinders help prevent confusion and ensure that the correct gas mix is used during a dive. The MOD indicates the maximum depth at which the gas blend is safe to use. Clear visibility of the MOD helps divers avoid accidentally exceeding the limits of their gas mixture, which could lead to serious safety risks such as oxygen toxicity or decompression illness.
6. What are the benefits of using nitrox and trimix gases in scuba diving?
Nitrox is a gas blend commonly used in recreational diving, containing a higher percentage of oxygen (up to 40%) than regular air. Nitrox allows for longer dive times and reduces the risk of decompression illness. However, it requires careful monitoring of oxygen levels to avoid oxygen toxicity. Trimix is used by advanced technical divers for deep diving beyond 60 meters. It consists of oxygen, nitrogen, and an inert gas like helium. Trimix enables precise control of oxygen levels for safer deep dives. However, due to the scarcity of helium and custom-blending, trimix can be relatively expensive.
