Oxygen concentration alarm

The oxygen concentration alarm detects ambient oxygen levels through an electrochemical sensor and triggers audible and visual alarms when the concentration falls below the safety threshold. It is used for monitoring confined spaces or oxygen-deficient environments to ensure respiratory safety. It is commonly found in laboratories, warehouses, underground operations, and similar locations.
Selection
When selecting, ensure that the range covers 19.5% to 23.5%, and check the sensor lifespan and calibration cycle. Pay attention to matching the explosion-proof rating with the usage environment, and compare response times and alarm error values. Confirm that the product has self-test functionality and fault alerts, and check whether the protection rating is suitable for the on-site environment.
