Dust concentration detector for rapid detection of occupational health particulate matter concentration

Dust concentration detector for rapid detection of occupational health particulate matter concentrationLD-8The Type Dust Concentration Detector is a rapid dust detector suitable for occupational health dust concentration detection. 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.Dust concentration detector for rapid detection of occupational health particulate matter concentrationThis instrument is suitable for rapid detection of dust concentration in the ambient air by comprehensive administrative law enforcement personnel in occupational health and ecological environment protection. It can also be used in public places (hotels, shopping malls, restaurants, office buildings and other places with high traffic volume), third-party testing institutions, university research institutes, shipbuilding, aviation, precision semiconductor manufacturing, grain processing, aluminum powder polishing, petroleum and petrochemical industries, etc.
