MISSION: QS Fibre Inc strives to help mill operators around the world make their pulp, paper, and board,   ...BETTER!   

We go about it by providing pulp and paper mill operators with the means to quickly determine sources of fibre quality variability and zero in on their causes. Our QS Fibre Classifier (QualScan III) maps fibre distributions by length, width, and shape. When changes occur to these distributions, operators are quickly alerted. The nature of the change provides diagnostic clues and enables troubleshooting teams to immediately trace back through the fibreline or stock prep until the root cause is isolated and corrective or remedial action is determined and taken. Our dedication to continuous product development and improvement will be showcased at our grand new product launch 21 May 2017.

Through the fibreline and stock prep on to the reel: fibre is the  1 common  denominator 

QS Fibre help our clients build a comprehensive fibre knowledge base.  

QS Fibre help our clients act to influence causes and shape their effects.
