What does an oxygen concentration meter measure?

An oxygen concentration meter specifically measures the level of oxygen in the air or a given environment. This is critical in various settings, including industrial or medical environments, where oxygen levels can significantly impact safety and health. A concentration above a certain threshold, such as 25%, can pose serious health risks, including increased fire hazards and potential for oxygen toxicity.

By accurately gauging oxygen levels, these meters help ensure that environments are safe for individuals, enabling timely interventions if oxygen levels exceed safe thresholds. This focus on maintaining appropriate oxygen levels is vital for both human safety and for maintaining the integrity of some processes that may be sensitive to oxygen concentrations.

Other measurement options listed, such as detecting toxic gases, moisture levels, or temperature changes, refer to different types of meters that are designed for those specific purposes and not for measuring oxygen concentration. Therefore, their functionalities are distinct from that of an oxygen concentration meter.
