Canadian Freeness Tester
 

Digital Model (T) with Temperature compensation

Manual Model (M )

 

Description

The Canadian Standard Freeness Tester measures the degree of work done on the fibres during stock preparation (refining) and is therefore a primary tool in the evaluation of the characteristics of pulp. The apparatus consists of a drainage chamber and rate measuring funnel on a sturdy support. 1 litre of pulp suspension at 0.3% concentration drains through a perforated screen plate into a funnel provided with a bottom and a side orifice. The discharge from the side orifice is collected in a graduated cylinder, measured by an ultrasonic sensor and the result displayed digitally. The actual temperature of the suspension is measured simultaneously and the result corrected automatically. Any deviation from 0.3% is entered at the digital control panel before reading the fully compensated result in ml CSF.
