PURPOSE: A device for measuring particle materials of exhaust gas is provided to comprise a plurality of filter units for alternate use, thereby continuously measuring a sample regardless of the replacement of a filter unit in which collecting the particle materials is completed. CONSTITUTION: A device(100) for measuring particle materials of exhaust gas comprises a dilution tunnel(110), a distributing pipe(119), a flow rate measuring unit(170), filter cartridges(131a,131b,131c), and connection pipes(133a,133b,133c). The exhaust gas and external air, targets for an inspection, flow into the dilution tunnel, thereby being diluted. The distributing pipe is connected to an outlet of the dilution tunnel. The flow rate measuring unit measures a flow rate of diluted gas discharged from the dilution tunnel. The filter cartridges are detachably connected between the distribution pipe and the flow rate measuring unit. The filter cartridge comprises a filter bed collecting particulate materials included in the diluted gas discharged from the dilution tunnel. The connection pipe is arranged in between the filter cartridges and the flow rate measuring unit. The connection pipe is bent or the length of the connection pipe is varied so that the filter cartridges can be demounted or mounted.
