About This

• First-Time Startup Notice: To ensure measurement CO2 detector accuracy, let the device sit undisturbed for 5–10 seconds after first power-on. It will then automatically begin a 200-second calibration to adapt to the environment and eliminate system errors. ▲ During calibration, place the device in a well-ventilated area (open the window) with no one nearby. This ensures accurate results. Calibrate once every 2–3 months to maintain optimal detection accuracy.
• Manual Calibration: 3-in-1 Air Detector supports a manual calibration function, which is simple and convenient to operate. Long-press the left button for 5 seconds to enter the 200-second manual calibration process. It can be independently calibrated according to different usage environments (home, RV, confined space, etc.) to ensure that the detection CO2 Value is always accurate and reliable. No professional operation is required; you can complete the calibration by yourself, adapting to the monitoring needs of different scenarios and avoiding detection deviations caused by environmental differences.
• Plug-in Design: Carbon dioxide detector plug-in features a plug-in design—it powers on instantly when plugged in and shuts off when unplugged—achieving "zero-barrier" operation that requires no tedious configuration, making it extremely simple to use. Equipped with 110~220V wide voltage adaptation, it can be easily used in various scenarios such as international travel, home and RV. Small and lightweight at only 60g, it is portable and does not take up space, allowing you to test wherever you go. Say goodbye to battery life anxiety and continuously protect air safety.
• Custom Threshold: CO2 monitor supports custom setting of CO2 value. Long-press the middle button to enter the setting mode. The 4-digit value can be adjusted accurately. Each press switches the digit for confirmation, and the right button is used to increase the value from 0 to 9 incrementally, adapting to the personalized needs of different people and different scenarios. When the CO2 value exceeds the set threshold, it will immediately trigger an 85-decibel sound and light reminder + red bar flashing. At the same time, the buzzer can be manually turned off, flexibly balancing warning and tranquility to avoid unnecessary disturbance.
• High-Precision Monitoring: Indoor Air Quality Meters adopt a high-precision CO₂ detection sensor, achieving ±5 ppm accuracy with a measurement range of 400–4999 ppm — far superior to ordinary meters. The device supports high-frequency data acquisition every two seconds, capturing subtle real-time fluctuations in CO₂, temperature, and humidity. This eliminates data latency and errors, ensuring consistently precise readouts and a more reassuring indoor environment for your family.
• High-Definition Large Screen: Air Quality Meters equipped with a 2-inch color screen design, it clearly displays real-time data of CO2 concentration, temperature, and humidity with distinct colors for easy identification—green for safety, yellow for early warning, and red for reminder, allowing you to intuitively grasp the air status.
