This product is a multifunctional air quality monitor that detects Carbon dioxide (CO2),Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC),
Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality
detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO2), formaldehyde (HCHO), total
volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.
