AQ Guard is currently the most advanced compact aerosol spectrometer for determining pollution by particulates using 90 Degree optical light scattering, and single particle counting (Its not a nephelometer!!). AQ Guard is offered in two versions: Indoor Air and Outdoor Air. Both models have integrated touch screen displays and measure PM2.5 and PM10 data simultaneously. Fine dust professional package with other PM values and particle size distribution is available as an option from 0.175 to 20 microns. AQ Guard has a built-in PC, therefore no cloud services are required. AQ Guard is equipped with temperature, atmospheric pressure, and relative humidity sensors. AQ Guard: Indoor Air can be upgraded with the Healthy Rooms package for CO2, TVOC, Air Quality Index, and patent pending germ indicator. AQ Guard Ambient: Outdoor Air is equipped with a protective cover and a compact IADS to compensate for humidity influence on PM data even at 100% Rh and eliminates fog droplets.
