Carbon Dioxide Alarm Detector

Carbon dioxide alarm detectors measure gas concentration by absorbing specific wavelengths of infrared light through infrared sensors, emitting audible and visual alarms when concentrations exceed preset thresholds. They are used for indoor air quality monitoring, greenhouse farming, and safety protection during fermentation processes.
Selection
When selecting, ensure the range covers the concentration scope of the application scenario, check the sensor lifespan and calibration cycle, consider the compatibility between explosion-proof rating and the on-site environment, and verify whether the alarm logging function and output interfaces meet data management requirements.
