AQ Guard is currently the most advanced compact aerosol spectrometer for determining pollution by particulates in indoor air. Using the same measurement system and sophisticated algorithms as the EN 16450 certified Fidas® 200 it analyses continuously, reliably, and precisely airborne fine dust particles in the range 175 nm – 20 µm. The "ambient" version (with heated aerosol inlet) achieves precision comparable to type approved analyzers, which makes AQ Guard stand out compared to similar devices.
