Abstract

Sonde comprenant une pluralité d'électrodes détectrices discrètes et saillantes (34, 36) à sortie analogique disposées sur un boîtier renfermant un microprocesseur (16) et un convertisseur analogique/numérique (40) destiné à numériser les sorties des électrodes (34, 36). Un agitateur est entièrement intégré au boîtier et fait saillie à partir du centre de celui-ci de sorte que les électrodes l'entourent. Un moteur d'agitateur (60) et une commande d'agitateur (56) sont intégrés au boîtier. Le microprocesseur (16) commande les fonctions marche/arrêt, tension et vitesse de rotation de la commande d'agitateur (56). La sonde possède également un dispositif amovible d'étalonnage doté de cuvettes dont chacune peut recevoir une solution d'étalonnage différente de sorte que l'on puisse étalonner toutes les électrodes simultanément.
