Abstract

La présente invention concerne un dispositif d'analyse de liquide portable permettant de caractériser au moins deux propriétés d'un liquide, au moins l'une des propriétés étant une propriété physique. Une propriété chimique d'un liquide peut également être déterminée. Le dispositif comprend : un composant de test à main et un composant d'échantillonnage de liquide comprenant un ou plusieurs matériaux d'indicateur optique. Le dispositif peut en outre comprendre un lecteur optique qui mesure des propriétés optiques des matériaux d'indicateur optique dans le composant d'échantillonnage de liquide après que les matériaux d'indicateur optique sont exposés au liquide, un processeur de données et un dispositif d'affichage destiné à afficher des informations concernant le liquide à l'utilisateur. Des informations concernant les liquides peuvent être transmises à des emplacements externes ou peuvent être ajoutées par un utilisateur dans la mémoire du dispositif.
