The high-definition LED screen enables you to read data faster and more easily. There are 4 different color bars on the screen indicating CO2 concentration levels: green for healthy, yellow for attention, orange for ventilation and red for danger. This allows for a quick identification of the surrounding air quality. Before use, put the CO2 sensor in the vent for 5-10 minutes for data calibration, if the air quality changes, please wait 35 seconds for the detector to sense the change
Using NDIR non-scattering infrared sensor, CO2 detector has stable performance and high precision
Carbon dioxide detector real-time monitoring: real-time detection of indoor environmental quality, measured by three key indicators - carbon dioxide, temperature and humidity, comprehensive indoor air quality, to ensure breathing health
