Abstract
A device for measuring the particle concentration in an aerosol using a flow tube includes a cavity in which there is a sleeve, the cavity branching off from the flow tube. The sleeve includes, at its end facing away from the flow tube, a collar. The collar encircles the periphery of the sleeve and is fastened at the periphery of the cavity. There is one or more inflow openings in the collar. At least one outflow opening is in an end of the sleeve, which end extends into the flow tube. A measuring chamber is also included in the cavity on the side of the sleeve facing away from the flow tube.
