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