The type dust densitometer uses a light projector that individually projects several types of single wavelength light with different wavelengths, and a light receiver that can individually detect the transmitted light of those single wavelength lights. , parameters that are functions of particle size distribution, optical wavelength, refractive index, etc. related to the law that holds between optical density and mass concentration are calculated, and parameters that are related to the law that holds between optical density and mass concentration are calculated and What is claimed is: 1. A dust physical property measuring device connected to an arithmetic and control device that determines a correspondence between the two and determines physical property values such as dust mass concentration, particle size distribution, and refractive index based on the correspondence.
