1. A method for measuring the turbidity of a liquid sample by reflectometry, which comprises:
- passing a light beam through the liquid sample to a diffuse reflector which reflects the light in a diffuse manner back through the sample again and measuring the intensity of the light reflected in a diffuse manner and attenuated by the turbidity of the sample to determine the turbidity of the liquid.

Abstract
A method and a device for the measurement of turbidity in liquids is described, the measurement taking place by reflectometry. Reflectometers into which a cell and a diffuse reflector can be introduced are used. A method for the measurement of turbidity is described, for example for in-process controls or quality controls, which requires significantly less complex equipment than the conventional methods.
