Schopper-Reigler Freeness Tester

A Schopper-Riegler freeness tester is commonly used to quickly and accurately test the beatability of pulp that is associated with the pulp performance. This tester consists of a drainage cylinder in the upper section and a measuring funnel in the bottom section. On the border of the two sections, a specified type of wire cloth is installed. Inside the drainage cylinder, a conic valve is installed, which is operated using a pulley. The measuring funnel is cone-shaped, beneath which a small drain is provided. Another drain is also provided on its side, and an air pipe is provided above the drain. Each section is fabricated precisely to the given reference dimensions. The tester is retained on a stable base provided with a leveling device.
