Inhalable particulate matter analyzer for detecting dust, PM2.5, and other pollutants in the air

Inhalable particulate matter analyzer for detecting dust, PM2.5, and other pollutants in the airLD-7CThe inhalable particulate matter analyzer is a rapid particle detection instrument suitable for environmental monitoring in public places. The instrument adopts the principle of light scattering and is equipped with a calibrated optical stability self calibration device, which can eliminate the influence of temperature and humidity drift and achieve rapid determination of the concentration of particles of different sizes in the air.Inhalable particulate matter analyzer for detecting dust, PM2.5, and other pollutants in the airThis instrument can be used by occupational health law enforcement personnel to detect the concentration of inhalable particulate matter in indoor air, and is also suitable for public places (hotels, shopping malls, restaurants, office buildings, and other high traffic areas), third-party testing institutions, university research institutions, etc.
