Freeness Tester »Schopper-Riegler«

Device Description

This high quality product is characterized by the simplicity of operation. Only premium stainless steel, aluminum and POM (Polyoxymethylen – a highly resistant type of plastic) parts are being used for manufacturing this testing equipment. The sealing cone is raised automatically  by the switch of a hand lever (manual & pneumatic models). The filling chamber is placed and locked onto the funnel by a bayonet-lock. This allows a quick demounting of the filling chamber and to take out the sieve with the remaining fiber to make a dry content test. The calibrated nozzle exactly rinses 1000 ml in 149 seconds. The device is always delivered with two measuring beakers with both SR° and ml scale. Also see our digital version of the Schopper-Riegler Freeness Tester.

Test Description

The pulp suspension is poured into the closed drainage chamber on top of the funnel. By push of a button (digital) or the switch of a hand lever, the sealing cone is lifted and the suspension drains into the funnel. The fibers remain on the sieve placed between the drainage chamber and the funnel. The water is separated into the two measuring beakers that are placed under each orifice. The number of °SR can be read from the beaker that’s placed underneath the side orifice. Now the Bayonet locking can be opened and the sieve can be taken out for cleaning or to make a dry content test after drying the fibers.
