Abstract
A solution for measuring a suspension which contains wood fibres. The consistency of the suspension is changed in a consistency range. Optical radiation is directed at the suspension and the intensity of optical radiation interacted with the suspension is measured at different consistencies in the consistency range. The maximum intensity of the optical radiation is determined within the consistency range. At least one of the following properties of the suspension are determined based on the determined maximum intensity: kappa number, brightness.
