Claims

[Scope of Claim for Utility Model Registration] A measurement hole through which gas containing dust passes is provided in the center of a cylindrical container in the transverse direction of the container, and a measurement hole through which gas containing dust passes is provided at both ends of the container. A measurement section is provided that emits a light beam that crosses the gas and receives a light beam that crosses the gas, and a partition plate with a through hole through which the light beam of the measurement section passes is provided at both ends of the measurement hole of the container. A dust concentration measuring instrument is formed in which a clean gas supply path is connected to the cylindrical passage through which the gas containing dust flows, and the clean gas flows out from the through holes of both partition plates to the measurement hole side. A mounting hole is provided in the transverse direction of the passageway, and the above-mentioned measuring instrument is installed through the passageway's mounting hole, so that the penetration direction of the measuring hole of the measuring instrument matches the flow direction of the passageway, and both sides of the measuring instrument are separated. A dust concentration measuring device characterized in that a plate is placed on a peripheral wall of a passage.
