Beating & Freeness Tester isdesigned to determine the rate of drainage of a dilute pulp suspension andexpress it in terms of the Schopper - Riegler (ÃÂ°SR) value. The ÃÂ°SR value is theinverse of the volume of water collected (divided by 10). The rate of drainageis related to the work done on the fiber during beating and refining.
Sample:Â 2 gm. Oven dried
Reproducibility:Â approximately 1 0SR
