摘要

A measuring arrangement for determining organic and inorganic constituents of water in standing or flowing bodies of water comprises at least one light source (1) directing light via at least one collimating optical element (2) through the water parallel to one or more optical detectors (3) for wavelength-resolved measurement of the intensity of the light incident on the optical detectors. Preferred Features: The collimating optical element is an achromator. An optical filter (4) selective for different wavelengths is arranged in front of each detector. One optical detector is a spectrometer. The light source is a white light source.
