Overview
The Canadian Standard Freeness Tester (CSF Tester) by QGI is a high-accuracy laboratory instrument designed to measure the freeness and drainage characteristics of pulp fibers used in the paper manufacturing process. This equipment determines the Canadian Standard Freeness (CSF) value, which indicates the rate at which water drains from a pulp suspension and helps evaluate the level of mechanical treatment applied during pulp refining.
Engineered for precision and consistency, the QGI CSF Tester is widely used for testing wood pulp, groundwood pulp, mechanical pulp, and recycled fibers in paper and pulp laboratories. By providing a reliable index of pulp drainage behavior, the instrument assists paper manufacturers in monitoring refining efficiency, maintaining pulp quality, and optimizing the beating process for improved paper strength and formation.
The tester is equipped with a standard screen plate and a transparent Plexiglas measuring cylinder, allowing operators to observe and record accurate Canadian Freeness values with ease. Built with durable materials and designed for long-term laboratory performance, this equipment ensures stable and repeatable testing results in both research and industrial environments.
