This product is a multifunctional air quality detector that can detect total ozone (O3) volatile organic compounds (TVOC), particulate matter less than 2.5 microns in size (PM2.5 / 1.0 / 10), temperature and humidity, clock and recording functions. As a scientific air quality testing equipment, it combines multiple air sensors and built-in sensors. The fan can monitor ozone (O3), total volatile organic compound (TVOC), PM2.5/1.0/10/10, temperature and humidity on its digital LCD display.
