AQ Guard

Palas® introduces AQ Guard Ambient, a measuring device offering reliable and precise information about air quality. Versatile and suitable for a variety of applications in monitoring ambient air quality.
Air quality analyzer for monitoring indoor air quality of fine dust from a particle size of 0.15 µm, measurement of CO2, calculation of air quality index

AQ Guard, currently the most advanced compact analyzer for determining indoor air quality, continuously and reliably analyses airborne fine dust particles in the range 0.175 – 20 µm (*1 IAHP-Package starting from 0.15 µm). A newly developed mass conversion algorithm calculates PM values based on single particle optical light scattering, considering signal duration and shape.

AQ Guard simultaneously calculates and stores PM1, PM2.5, PM4, and PM10, the total dust load, the particle number concentration CN, and the particle size distribution. Thus, AQ Guard provides comprehensive, accurate information on indoor particulate matter. This is only possible in this form with a counting single particle measurement method.
