CO2 Levels

  • CO2 is present in ambient air at a background concentration of around 400 ppm (0.04%). In any enclosed environment the concentration will increase in excess of 1000ppm (0.1%) if the room is poorly ventilated well.Carbon dioxide (CO2) is not harmful to human body when it is low, but when the concentration reaches 1500-2000ppm, people will feel wheezing, headache, and dizziness.And higher levels are serious harmful to health.
    • 🔔 Fast Response and High Sensitivity The CO2 detector uses high-precision NDIR sensor to accurately monitor carbon dioxide concentration, and provide you the CO2 risk warning effectively.
    • 🔔 Large Digital Display and Easy Read 2.8 inch TFT full colour screen clearly displays the real-time CO2 concentration, temperature, and humidity from the surrounding air, respond to the CO2 meter threshold, and ensure your safety and health.
    • 🔔 Advanced NDIR CO2 Sensor The CO2 monitor uses advanced NDIR technology which has high reliability and long service life. When the CO2 level exceeds 1000ppm, the color of the CO2 number changes from white to yellow, orange or red to alert the air pollution.
    • 🔔 Widely Used Places Small size, portable and desktop use, suitable for indoor or outdoor carrying, detection of carbon dioxide (CO2) in home, office, school, car and other places.
