Abstract

The invention relates to a system for checking a suspension of solid particles, having a test tube for taking up and sedimentation of the suspension, having--an illuminating radiation source (L),--a test tube (P) is transparent to the illuminating radiation and the radiation emerging thereof, in which test medium is allowed to sediment and which can be located in the radiation path of the system,--optionally, a further test tube (PE), that is transparent to the illuminating radiation and the radiation emerging thereof, in which a reference or calibration liquid is allowed to sediment and which can be located in the radiation path of the system,--a sensor device to detect the illuminating radiation (S.sub.L)--a sensor device for detecting radiation emerging by transmission (S.sub.T) from the test tube(s) (P.sub.E, P)--a sensor device for detecting the radiation (S.sub.F) emerging from the test tube(s) at an angle other than 180.degree.--a timer device (U) and--a computer (R) for processing the measured values obtained and outputting at least one output signal to the processing unit.
