In this paper we present a description of a laser densitometer, its characteristics, and results of its metrological tests. This densitometer has been designed for measuring the mass concentration of dust. It uses photometric principle insrtumentally performed in a multipass cell. The range of mass concentration values detectable with the densitometer is from 3 to 18 mg/m3, the rms deviation of measurements being 25 per cent.
