Fixed oxygen alarm.

The fixed oxygen alarm detects the concentration of oxygen in the environment through an electrochemical sensor and emits audible and visual alarms when the concentration exceeds the preset range. It is used in confined spaces, laboratories, and other areas where oxygen levels need to be monitored to prevent safety incidents caused by oxygen-deficient or oxygen-rich environments.
Selection
When selecting, consider that the detection range should cover 19.5%–23.5% VOL, and it must have explosion-proof certification and an IP65 protection rating. The sensor lifespan is approximately 2–3 years, and a calibration interface should be reserved. The installation location should avoid ventilation outlets and corrosive gases, and wiring must comply with zonal explosion-proof requirements.
