Oxygen Concentration Detector and Alarm

The oxygen concentration detection alarm measures the oxygen content in the air using an electrochemical sensor and triggers audible and visual alarms when the concentration falls below or exceeds the set threshold. It is used in confined spaces, laboratories, and other environments to prevent safety incidents caused by oxygen deficiency or excess.
Selection
When selecting, confirm that the range covers 19.5% to 23.5%, verify that the explosion-proof rating matches the location, inspect the sensor lifespan and calibration cycle, ensure that the alarm values are adjustable and include a self-test function, and confirm that the product certifications comply with local safety standards.
