derlichen Störgrößen, wie sie z. B. durch Ablagerun- Die Erfindung ist im folgenden an Hand einesThe invention relates to a turbidity meter with 50 speed of the liquid to be measured within the control device, which is particularly increased for measuring the cuvette area so that the degree of turbidity of liquids with a high risk of contamination of the cuvette turbidity content is suitable. It consists of a well-known ten window, which is penetrated west ray when measuring liquids with way from a cuvette, which is particularly large by a measuring light very high proportion of turbid matter, and is significantly reduced to the side of the 55. The light-electric walls of the cuvette, which are arranged in a small dimension measuring light beam, secondly have the effect of the ler, which is greatly reduced by an absorption transverse to the measuring light beam, and thirdly, the control light beam running across is influenced. The opacimeter according to the main patent application fixing the cuvette within a plastic P 15 47411, the pressure resistance is significantly increased to compensate for blocks that change over time, without additional effort,
