Our AERASGARD® fine dust sensors reliably detect the concentration of particles in the air, making an important contribution to health protection. The devices use precise optical sensors to measure fine dust particles (PM1.0, PM2.5, PM10) in a range from 0.3 to 10 micrometers. They are ideal for use indoors, in offices, schools, public buildings or intelligent building systems. Depending on the model, output is via a standardized signal (e.g. 0-10 V or 4...20 mA) - sometimes supplemented by digital interfaces or switching outputs.
