Abstract
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 in suspension is one by one optically measured by a line camera in a thin equilateral capillary tube. The fiber-like particles in particular are imaged by two or more cameras in the capillary tube one or more times for measuring such properties as fiber thickness, wall-thickness and fibrillation.
