ABSTRACT:
The invention relates to an apparatus and method for measuring the properties of fiber pulp. The apparatus used in the method comprises a batching vessel (1) for measuring the volume and temperature of the sample; a filtering chamber (3, 5) by means of which the sample is filtered on a wire (4) by means of a pressure difference, and an air flow is produced through the pulp cake formed during the filtration. The apparatus has, next to the filtering chamber (3, 5), a raisable vertical central shaft (8), which can be rotated in steps, and holders for transferring the wire (4) together with the pulp cake to positions around the central shaft (8) for the functions, and for returning the wire (4) into the filtering chamber.
