The invention is an instrument measuring the concentration of fine particles in the air. It consists of an aerodynamic stage screening device directing aerosol particles according to their mass to microbalances. The choice of this instrumentation is in accordance with the standard procedures used in the field of aerosol measurement to evaluate indoor air quality. The desire to target aerosols of biological origin such as microfungi is linked to health issues, as these microbes cause allergies. Real-time and continuous monitoring of the presence of particulate matter in the air will allow more accurate analysis of outdoor and indoor air quality.
