Device description
The digital model of the Schopper Riegler Freeness Tester stands out for its intuitive and easy operation via the integrated 10-inch touchscreen and the pre-installed measurement software. The measurement process can be controlled via the display, and the measurement data can be presented in graphs and statistics. The device is also equipped with a high-precision scale to ensure the most accurate results and high test repeatability. The drainage chamber is easily removable, allowing the sieve with the remaining fibers to be quickly removed for dry matter content tests. The nozzle, calibrated to ISO standards, flushes exactly 1,000 ml in 149 seconds, and the grind size can be read in °SR and ml on the two measuring cups included.
