[Product Overview]
The FST100-2005 air quality sensor is designed based on the principle of laser scattering and is mainly used to detect the content of PM 2.5/PM10 particles in the atmosphere. The product adopts a high-sensitivity gas detection probe, with stable signal, high accuracy, wide measurement range, and long transmission distance. Suitable for air quality and environmental monitoring in factories, schools, shopping malls, construction sites, and other places.
