SR-1 (Pneumatic)
Pneumatic Freeness Tester (Schopper-Riegler)
The SR-1 Pneumatic Freeness Tester determines the degree of refining and drainage speed of paper fibres by the Schopper-Riegler method, with pneumatic actuation for faster, more consistent testing. Its POM drainage chamber and adjustable closing cone speed (standard 100mm/s) suit high-throughput pulp laboratories.
Pneumatic Freeness Tester (Schopper-Riegler Method)
Pneumatic equipment for determining the degree of refining and the speed of drainage of paper fibres by the “Schopper-Riegler” method. Robust equipment built in stainless steel, designed for ease of operation and cleaning, with pneumatic actuation of the release and closing system for consistent, repeatable testing.
Key Features
- Robust equipment built in stainless steel.
- Drainage chamber in POM material (Polyoxymethylene “Polyacetal”).
- Adjustable closing cone speed (standard 100mm/s).
- Pneumatic actuation of the release and closing system.
- Direct reading of the degree of refinement from the graduated glass.
- Ease of operation and cleaning.
Applications
Ideal for pulp mills and paper manufacturers requiring consistent, repeatable Schopper-Riegler testing at higher throughput than manual models. Meets BS 6035/1, ISO 5267/1, NF Q 50-003 and SCAN C 19/M3.
