In this paper a new device for health related dust measurement at workplaces is described. The instrument is a personal dust monitoring and sampling system. The inhalable, the thoracic and the alveolar fraction of the airborne dust are simultaneously sampled, and monitored on-line. The sampling characteristics of the device follows the convention of the European Standard EN 481. The measuring principle is a combination of inertial classification and concentration enrichment using a virtual impactor, filter sampling and aerosol photometry. The instrument is described in detail and the results of test and calibration measurements as well as measurements at workplaces are presented.
