Abstract
A particle-measuring apparatus () has an optical particle sensor (). By means of the optical particle sensor () a particle mass concentration in an aerosol volume can be detected. Furthermore, the particle-measuring apparatus () has a measurement chamber (), in which the aerosol volume to be examined with regard to the particle mass concentration by means of the optical particle sensor () can be received, and a conveying device (), by means of which the aerosol can be introduced into the measurement chamber (). In order to prevent the particle-measuring apparatus () from being adversely affected during operation as a result of dirt or particle deposits, it is proposed that the delivery rate of the conveying device () of the particle-measuring apparatus () is adjustable.
