Measures the Canadian Freeness number which is a measure of the drainage capacity of different pulp types. The
drainage rate has been shown to be relatedto surface conditions and swelling of the fibres. It is also useful index of the
amount of mechanical treatment given to the pulp and express CSF.

Freeness: A known volume of pulp in aqueous suspension is drained through the fibre mat on a standard perforated
