Air Quality Monitor Indoor for CO2, Temp, Humidity, YOWEXA 400-10,000 PPM Carbon Dioxide Detector with NDIR CO2 Sensor & Color Screen, 3 Adjustable Backlight CO2 Monitor for Home/Office/Car/Plant
【High-Precision NDIR Sensor】Our CO2 meter features high-precision&intelligent algorithm NDIR sensor, enabling automatic calibration, temperature/component aging, and strong anti-interference capabilities. The longer it operates, the greater its stability, reducing maintenance requirements. Range: 400-10,000 PPM; Accuracy: ±5% + 50 PPM; Measurement Interval: 4S; Response Time: 3min; Refresh Rate: 1S
【HD Color Display with 3 Adjustable Backlight】The YOWEXA carbon dioxide monitor boasts HD color screen with a sleek, stylish appearance. Three adjustable backlight accommodate varying lighting conditions, making it ideal for placement in living room, bedroom, and nursery room. Ensures clear visibility during the day while eliminating light pollution that could disturb sleep at night
【Emoticons Make Value Visual and Kid-Friendly】The air quality meter links CO2 levels to different emoticons, providing an intuitive way to monitor the extent to which CO2 concentration affects health—especially easy for children to grasp. Effortlessly safeguard your family's well-being
【CO2 Concentration Alarm with One-Touch Mute】High CO2 levels may cause headaches, drowsiness, allergies, and loss of concentration. When CO2 concentration≥1000PPM, the air tester will automatically sound an alarm for 10S, prompting you to open windows/doors for ventilation. This reduces CO2 levels indoor, restores energy and boosts efficiency. Short press the power button to silence the alarm and avoid disturbing others
【400PPM Manual Calibration for Enhanced Accuracy】The NDIR sensor offers extremely user-friendly 400PPM calibration mode, enabling rapid adaptation to varying operating environments. ① Place outdoors and operate for at least 10 min ② Press the calibration port with a needle for 5–8S ③ Release when “CAL” flashes on the screen ④ When complete,return to normal display automatically (Outdoor CO2 concentration is approximately 400PPM)
【Two Power Supply Options for Flexible Use】The air quality detector supports direct charging via lithium battery or USB power supply, allowing flexible use based on actual conditions. We recommend primarily using USB power to avoid device shutdown and inoperability due to forgotten charging
【NOTE】NDIR sensor technology enables CO₂ sampling intervals as short as 4S—top-tier speed and accuracy in CO2 monitor market. So, the battery life remains up to about 6-12h after a full charge. (Enough for use on the way or emergencies)
