Compact Desktop Air Quality Monitor is designed to accurately measure the Indoor Air Quality Index as well as dust,  particulates, volatile organic compounds and the overall air quality of your environment.

With easy to read graphics and a large, bright color LED display, this monitor can detect PM 1, PM 2.5, PM 10 (particulate matter), TVOC (total volatile organic compounds), HCHO (formaldehyde), temperature and humidity with high sensitivity, stability and response speed. Also calculates the Air Quality Index and displays this reading using a color-coded bar graph.

The unit combines multiple air sensors with a super quiet, built-in fan to allow realtime monitoring, and also has an auto calibration function. Perfect for home, office, newly furnished houses, kitchens, bedrooms, commercial spaces and classrooms.

Compact size fits on any desk, nightstand or tabletop, and the unit features a rechargeable lithium-ion battery with micro-USB charging cable and a low battery indicator on the display. The monitor also self-calibrates with a double press of the power button.
