Frequently Asked Questions

Which instrument is used for gas analysis?

In diving, gas analysis is crucial for safety and efficiency, and various instruments are used for this purpose. The most common is the oxygen analyzer, which measures the oxygen content in a breathing gas mix to ensure it is safe for the intended dive depth. Other important devices include helium analyzers and carbon dioxide monitors, which check for the presence of these gases to prevent toxicity and hypercapnia respectively.
