1. A device for gas-dust impurities measurement composed of heads with a illuminator and a detection unit, located in a straight line exactly one opposite another and perpendicularly in relation to the flow of exhaust fumes in waste-gas pipe, which are equipped with sections of measurement pipes of ends located right next to optical windows of the heads and which has a control pipe, characterised in that sections of measurement pipes (7 and 8) are located one independent from another on two parallel paths of light beams and are set in pairs in each head, however, sections of pipes (8) forming the proper measurement unit are equipped with outlet slots (15) for the air, and sections of pipes (7) used to continuous resetting of the device are located in a control pipe (9), whereas the control pipe (9) is attached permanently in the waste-gas pipe.<IMAGE>
