This product is a multifunctional air quality detector 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 CO2 (carbon dioxide), formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.
