SR Freeness Tester

    PN-SDJ100 Beating Freeness Tester is designed to determine the rate of drainage of a dilute pulp suspension and express it in terms of the Schopper-Riegler(SR) value. The tester obeys the related prescriptions mentioned in ISO 5267/1 and GB3332.
    The Schopper-Riegler test is designed to provide a measure of the rate at which a dilute suspension of pulp may be dewatered. It has been shown that the drainability is related to the surface conditions and swelling of the fibre, and constitutes a useful index of the amount of mechanical treatment to which the pulp has been subjected.
