Abstract

L'appareil comprend une cuvette de mesure faisant partie d'un bloc de mesure pouvant être maintenu à une température modérée, un dispositif d'agitation, un dispositif optique de mesure de la turbidité. Il présente une combinaison des caractères suivants: Le dispositif d'agitation (16) est du type magnétique en soi connu; il est placé dans le bloc de mesure (11), au-dessous du canal (8) de réception de la cuvette de mesure (17). Un agitateur, constitué par une bille de métal (23), est disposé dans la cuvette de mesure (17). Il est mis en mouvement par effet magnétique au moyen du dispositif d'agitation (16). La cuvette de mesure (17) est maintenue dans le canal de mesure (8) au moyen d'un dispositif de blocage (18). Elle est disposée dans la trajectoire du faisceau lumineux (32) d'un dispositif de détection optique (13) dont la source de lumière (15) est alimentée par une tension de service au moins égale à la moitié de la tension nominale. Le récepteur de lumière (14) est relié à un indicateur de la valeur mesurée (27). Le bloc de mesure à température modérée peut aussi comprendre un bloc de cuvettes amovible (39) muni de plusieurs canaux (8, 8a) pour plusieurs cuvettes de mesure (17). A chaque cuvette de mesure (17) disposée dans son canal (8a) est associé un détecteur particulier du dispositif de détection optique (13). Celui-ci est relié à un microprocesseur (43) ou analogue, pouvant être actioné au moyen d'un organe de commande (44) et qui est relié à un dispositif de sortie des données. Ce dispositif de sortie des données peut être une imprimante (31) et/ou un écran d'affichage (46).
