Freeness

Measuring pulp freeness analyses the drainage capabilities with which water drains from a pulp sample. This helps paper mill managers control their paper machine runnability, leading to better quality and more saleable paper.

Both the CSF-20 Canadian freeness tester and Schopper-Riegler Type freeness tester are widely used to track the changes in the drainage rate of various chemical pulps during beating and refining. However, the pulp samples for the Schopper-Riegler have a lower concentration and the scale is reversed.

Calibration support is also available for your freeness tester apparatus, which is critical to achieving precise test results.
