After analyzing enriched air, what should you compare the oxygen percentage with?

After analyzing enriched air, it is essential to compare the oxygen percentage with the percentage marked on the contents sticker or tag. This comparison ensures that you verify the actual oxygen content in the tank against what is documented on the label. The contents sticker provides critical information regarding the composition of the gas, which is vital for safe diving practices.

By confirming that the analyzed oxygen percentage aligns with the marked value, divers can ensure they are using the correct mix for their planned dive. This is particularly important for managing exposure to oxygen and preventing potential issues such as oxygen toxicity during deep dives.

While there may be considerations regarding estimated amounts based on depth, readings from other analyzers, or maximum recommended depths for diving, these factors do not directly validate the specific oxygen content of the gas in your tank, making the contents sticker the most relevant and practical source of information for this analysis.
