  • 【Reminder】YOWEXA CO2 Monitor is specifically designed for monitoring CO2 concentrations. CO2! CO2! CO2! Please carefully verify before purchasing!
  • 【USB-powered Only】Continuous power supply via USB ensures round-the-clock monitoring without interruption, keeping the device active at all times and preventing any air quality data from being missed. (In emergencies, it can be used in battery charger mode, but this will only last for about 2 hours, please consider this carefully!!!)
  • 【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. NOTE: Press the power button twice within 1S to turn off the alarm function
  • 【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)
  • 【Lifetime Sales Support】YOWEXA provides a 36-Month worry-free sales service, lifetime technical support for this item. Please feel free to contact us if you have any concerns
  • 【Tip for Hot & Humid Areas】It is normal for CO₂ levels to rise to 1500–2500 ppm in tightly sealed rooms with windows closed. Readings dropping back to 400–500 ppm after ventilation confirm the sensor is working properly. In regions with long-term air conditioning and closed windows (such as Florida), CO₂ buildup is common and needn't worry about acute health risks. You can improve air quality using fans, exhaust fans, or HVAC fan mode without opening windows
