Accurate measurement and monitoring of particulate matter enabled air quality assessment and identification of potential environmental exposures. In healthcare, particulate matter measurements contribute to the detection of particle pollution and allow for better assessment of respiratory risks. In addition, particulate matter measurements are very relevant in industry, construction projects, indoor environments and laboratories to minimize the impact on employee health and to control laboratory/production conditions. Our "Particulate-Hygro-Thermo-Baro Sensor" not only enables precise measurement of fine dust, but also provides humidity, temperature and air pressure measurement functions.
