Canadian Freeness Tester

Manual equipment for determining the degree of refining and the speed of drainage of paper fibres by the Canadian °CSF method. The values obtained (°CSF or ml) measure how effectively a pulp suspension performs dewatering — a useful index of the work done on the fibre during beating or refining.

Based on the TAPPI T227 and ISO 5267/2 standards, 3 dry grams of paper pulp are diluted in water and poured into the drain container. The upper lid closes, the lower lid opens, and the suspension flows onto the calibrated sieve plate for measurement.

Key Features

  • Manual operation, robust and easy to use.
  • 1000ml cylinder.
  • 23.5ml cone volume.
  • 0.5mm sieve plate perforations.
  • Mounted on a robust stainless steel frame.
  • Complies with TAPPI T227 and ISO 5267/2.

Applications

Essential for pulp mills and paper manufacturers assessing the degree of refining in the pulping process, providing a standard measure of drainage rate that indicates fibre treatment level.
