Tips: Why is the sensor not affected by other gases?

The sensor's design incorporates a high level of cross-gas immunity, meaning it is selectively sensitive to oxygen molecules while ignoring other gases that might be present in the environment. This is achieved through its specialized fluorescence-based detection technology, which relies on oxygen-specific interactions rather than chemical reactions. This makes the sensor highly reliable in environments where multiple gases coexist, such as industrial processing plants, automotive exhaust monitoring, or inert gas chambers.
