About this item

• Carbon dioxide semiconductor: use advanced sensors to accurately detect and measure various air pollutants and environmental factors, with a sensitive response to detect every second, and can detect all irritating gases, such as carbon dioxide, alcohol, toluene volatiles, perfume, odor, etc. Cannot detect pure carbon dioxide gas.
• Easy to operate: Powered by a rechargeable battery, it allows for cordless use and is easy to carry at home or in the office. The battery has a capacity of 1200mAh and can last for 4-6 hours. The product comes with a USB charging cable. If you need to monitor an indoor environment for a long time, it is recommended to keep it charged.
• Comprehensive monitoring: measuring carbon dioxide（CO2）, formaldehyde(HCHO), Total Volatile Organic Compounds（TVOC）, temperature(TEMP), and humidity(HUMI), providing comprehensive analysis of indoor air quality to meet most indoor testing needs.
• ⚠️Note：This product uses a carbon dioxide semiconductor sensor that updates data every second and is susceptible to interference from various stimulating gases. It is recommended to place it in a ventilated environment at 400ppm for 20-30 minutes for calibration before placing it in the environment to be tested. If the data does not drop to around 400 ppm in a ventilated environment, double-click the power button and let it sit for another 20 minutes before use.
• Color LCD screen: Comes with a color digital display screen, showing real-time air quality readings for simple understanding and tracking of changes.
