Abstract
(DE)
Optisches Messsystem zur Bestimmung der Konzentration insbesondere trüber Flüsskigkeitsproben mit einem Messvolumen zur Aufnahme der zu messenden Flüssigkeitsprobe, mehreren Photometerkanälen, die jeweils eine Lichtquelle und einen Lichtempfänger auf verschiedenen Seiten des Messvolumens auf einer gemeinsamen optischen Achse aufweisen und deren optische Achsen unter verschiedenen Azimutwinkeln zum Messvolumen angeordnet sind, und einer Auswerteeinrichtung, welche die Konzentration der zu messenden Flussigkeitsprobe aufgrund der von mehreren, verschiedenen Photometerkanälen angehörenden Lichtempfängern gelieferten Messwerte ermittelt.
(EN)
The invention relates to an optical measuring system for determining the concentration of especially turbid liquid samples. The inventive measuring system comprises a measuring volume that receives the liquid sample to be measured, a plurality of photometer channels that are each provided with a light source and a light detector, disposed on a common optical axis, on different sides of the measuring volume. The optical axes of the photometer channels are disposed at different azimuth angles with respect to the measuring volume. The measuring system is further provided with an evaluation device which detects the concentration of the liquid sample to be measured on the basis of the values measured by a plurality of light detectors associated with different photometer channels.

L'invention concerne un système de mesure optique pour la détermination de la concentration, en particulier d'échantillons liquides troubles, comportant un volume de mesure destiné à loger l'échantillon liquide à mesurer, plusieurs canaux photométriques, qui comportent chacun une source de lumière et un récepteur de lumière placés sur différents côtés du volume de mesure, sur un axe optique commun, et dont les axes optiques sont disposés sous des angles azimutaux différents, par rapport au volume de mesure. Ce système de mesure comprend également un dispositif d'évaluation qui détermine la concentration de l'échantillon liquide à mesurer, sur la base des valeurs de mesures délivrées par plusieurs récepteurs de lumière appartenant à différents canaux photométriques.
