Freeness Tester

Various fiber slurries are cut, crushed, rubbed, split, moistened and refined to achieve cell wall displacement and deformation of fibers. Meet ISO 5264/I, TAPPI-T200, GB7980 and other laboratory beating standards, can change the heavy thallium pressure, beating time, and automatically control the beating time to obtain different experimental results.

Automatic control beating time, volume 23L, slurry amount 200g~ 700g, meet ISO 5264/I, TAPPI-T200 and GB7980 standards.
