Mütek DFR-05 Premium

The lab device BTG-Mütek™ DFR-05 Premium simulates the retention and drainage conditions prevailing in a paper machine immediately before and during sheet forming. Chemical addition is fully automatic via an integrated dosing module. The optionally available RET-20 Lab Sensor directly measures the filtrate consistency.
The drainage behaviour is characterized by gravimetry of the filtrate volume. Besides, the Schopper-Riegler freeness can be determined from which the Canadian Standard Freeness (CSF) may be calculated applying a correlation.
