Abstract

Measurement device for quantitatively detecting constituents of a pulp/fluid mixture for paper and/or cardboard production. The device includes at least one radiation source for irradiating the mixture in a number of definite, different wavelength ranges. The device also includes at least one sensor for measuring the intensity of radiation that has been influenced by the mixture, and at least one set of measurement electronics. Each sensor detects only one of the definite, different wavelength ranges of the radiation at a particular time.
