The invention relates to a method for measuring particles in suspension and a measuring instrument. In the solution the length of each fiber-like particle (210) in suspension is one by one optically measured by a line camera (304) in a thin equilateral capillary tube (308). The fiber-like particles (210) in particular are imaged by two or more cameras (304, 316, 318) in the capillary tube (308) one or more times for measuring such properties as fiber thickness, wall thickness and fibrillation.

Procédé de mesure de particules en suspension et instrument de mesure associé. Dans la solution, la longueur de chaque particule (210) de type fibre en suspension est mesurée de manière optique, séparément pour chacune des fibres, par une caméra de ligne (304), dans un tube capillaire équilatéral mince (308). Des images des particules (210) de type fibre en particulier sont produites par deux ou plusieurs caméras (304, 316, 318) dans le tube capillaire (308) une ou plusieurs fois, de manière à ce que soient mesurées des propriétés telles que l'épaisseur des fibres, l'épaisseur des parois et la fibrillation.
