What is the function of an oxygen analyzer?

The function of an oxygen analyzer is to gauge the percentage of oxygen in a gas mixture. This tool is essential for divers using Nitrox, as it allows them to ensure the correct oxygen levels are present in their breathing gas. Monitoring the oxygen content is crucial because the composition of the gas directly impacts a diver's safety and performance underwater.

Using an oxygen analyzer, divers can accurately determine the mix of gases they will be breathing, which helps prevent potential problems such as oxygen toxicity or hypoxia. Proper calibration and usage of the analyzer before a dive are standard practices in safe diving operations.

The other options, such as measuring pressure in the tank, analyzing nitrogen content, or measuring temperature changes, are functions not associated with an oxygen analyzer and pertain to other types of diving equipment or gauges. Each of these parameters is important in the context of diving but is managed by different instruments that serve distinct purposes.
