About This

• CO2 Monitor】This carbon dioxide monitor continuously measures CO2, air quality index, temperature, and humidity. With its real-time tracking and simple-to-read display, you can instantly see what’s in the air you’re breathing and ensure your indoor environment stays clean, safe, and comfortable.
• 【Swiss High-Precision CO2 Sensor】Equipped with a premium Swiss CO2 sensor, this air quality meter delivers fast and reliable readings every second. It measures CO2 levels from 400 to 5000 ppm with ±50 ppm precision, giving you dependable insight into yourenvironment. Combined with built-in temperature and humidity sensors, it provides a full picture of your indoor air health
• 【Emergency CO2 Alarm Protection】 This device serves as a safety alert system, warning you when carbon dioxide reaches hazardous levels caused by poor airflow, gas sources, or smoke intrusion. If CO2 rises beyond acceptable limits, it triggers an immediate audible alarm—giving you time to ventilate the area and protect your family
• 【Long-Lasting 1600mAh Battery】Powered by a rechargeable 1600mAh lithium battery, this monitor operates for up to 72 hours per charge. It features convenient USB charging and a lightweight design, making it easy to move from room to room or leave in a fixed location like your living room, office, or classroom
• 【Bright & Clear LED Display】Featuring a vibrant LED screen, this indoor air monitor clearly shows CO2 levels, AQI, temperature, and humidity in real time. Its sharp contrast and bright visuals ensure your readings remain easy to view at any moment—morning, night, or in low-light spaces
• 【Why CO2 Monitoring Matters】Normal CO2 levels are safe, but once concentrations rise beyond a healthy threshold, they can interfere with breathing and affect people, pets, and plants. In extreme conditions, dangerously high CO2 can pose serious health risks. That’s why tracking indoor CO2 levels is essential for maintaining a safe and comfortable living environment.
• 【Important Note】 Please be aware that CO2 monitors may show a slight reading difference of about ±50 ppm. This variation occurs because each meter uses its own sensor system. We appreciate your understanding and patience when comparing readings between devices
