Schopper-Riegler Laboratory Freeness Tester

The Schopper-Riegler freeness tester measures the drainage rate of pulp suspension on a standard screen plate to reflect the degree of fiber fibrillation. It is used in the papermaking industry for controlling the beating process, calculating the freeness value based on drainage time, and guiding the adjustment of pulp formulations.
Selection
When selecting, consider the type and concentration range of the slurry being tested, and match the instrument's measurement range. Check whether the sieve specifications meet the standards and confirm the sealing of the drainage system. The operation interface should be clear and easy to read, with accessories complete for convenient maintenance. Compare the measurement accuracy and stability of different models.
