What’s Analyzer?
In scuba diving, an analyzer refers to a device used to measure and analyze the composition of breathing gas within a scuba tank. Specifically, it is employed to determine the percentage of oxygen (O2) present in the gas mixture.
The analyzer typically consists of a sensor or probe that is inserted into the tank’s opening, allowing it to sample the gas. The device then provides a reading indicating the oxygen concentration. This measurement is crucial, especially when dealing with Enriched Air Nitrox (EANx) or other gas blends, as it ensures that the gas mixture adheres to the planned specifications for a safe and controlled dive.
Divers use analyzers during pre-dive checks to verify that the gas in their tanks aligns with the intended mix, helping to prevent issues related to incorrect gas blends. Regular calibration and maintenance of the analyzer are essential to ensure accurate readings and, subsequently, the safety of the dive.
