Product Description
This product is a multifunctional air quality detector that detects Ozone( O3), 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 device, it combines multiple air sensors with a built-in
fan to allow real-time monitoring of Ozone(O3), total volatile organic compounds
(TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.
2.8" crystal display (LCD), 320x240 pixels
User adjustable alarm threshold for Ozone(O3) to alert user of elevated
levels
variables: PM2.5/1.0/10, Ozone ( O3), TVOC, temperature, humidity
