9 IN 1 Air Quality Monitor Detector Formaldehyde HCHO CO2 Detect Meter Portable Carbon Dioxide with Temperature Humidity

【Compact and Convenient Design】 Our air quality detector features a sleek, small hook-up design that effortlessly attaches to your keychain, backpack, or belt. Take it anywhere you go, allowing you to monitor the air quality around you with ease.

【Cutting-edge Non-Dispersive Infrared (NDIR) Technology】Utilizing High-Accuracy NDIR technology, our detector provides real-time monitoring of CO2 levels, temperature, and humidity. This advanced technology ensures unparalleled accuracy and reliability, surpassing traditional electric-chemical sensors in carbon dioxide detection.

【Intuitive Three-Button Functionality】The "S" key serves a dual purpose – a short click to toggle the alarm on/off and a long press for data calibration. The "M" key on the CO2 monitor adjusts screen brightness with three levels to choose from, optimizing visibility while conserving power.

The Power button offers versatile functionality – a short click switches temperature display between and , while a long press powers the device on/off.

【Extended Battery Life】 Experience extended usage with our built-in large-capacity battery, providing an impressive 16-20 hours of continuous operation. A quick 4 charge ensures your detector is always ready for use. The intelligent alarm system activates when CO2 levels exceed 1500 PPM, prompting you to enhance room ventilation for a healthier environment.
