Abstract

Un capteur de turbidité (10) présente un boîtier (12), une cuvette (18) pour un milieu d’échantillon, un dispositif d’illumination (20), un capteur de lumière (21), un moyen de séchage (50) et un système à chambres (54). Le système à chambres (54) comprend un espace de réception central (28) dans lequel la cuvette (18) est agencée, une chambre d’illumination (42) à laquelle le dispositif d’illumination (20) est adjacent, au moins une chambre de capteur (44, 46) à laquelle le capteur de lumière (21) est adjacent, et une chambre sèche (52) dans laquelle le moyen de séchage (50) est agencé. La chambre d’illumination (42), ladite au moins une chambre de capteur (44, 46) et la chambre sèche (52) sont chacune en communication fluidique avec l’espace de réception central (28). Le système à chambres (54) est ici réalisé sous forme de système passif sans pompe. Figure 3
