The invention concerns a method which consists in: circulating in parallel, in a microchannel (126), a standard fluid (F2), whereof the rheological characteristics are known, as well as an unknown fluid (F1); identifying at least one data representing the interface (I) between said fluids, in the parallel flow, in particular the position of said interface; and determining the rheological characteristics of the unknown fluid based on the or each identified data.
Selon ce procédé : - on fait s'écouler en parallèle, dans un microcanal (126), un fluide étalon (F2) , dont les caractéristiques rhéologiques sont connues, ainsi qu'un fluide inconnu (F1) ; - on identifie au moins une donnée représentative de l'interface (I) entre ces fluides, dans l'écoulement parallèle, notamment la position de cette interface ; et - on détermine les caractéristiques rhéologiques du fluide inconnu, à partir de la ou de chaque donnée identifiée .
