The pulp freeness tester is a special instrument used to measure the rate of suspended pulp suspension water. Designed according to the internationally accepted principle of Schopper.
The instrument uses a manual compression seal cone to adjust the rate of ascent through a weight. Therefore the operation of the instrument is very simple. The instrument adopts a spring pre-tightening mechanism, so that the rubber sealing ring of the sealing hammer body is tightly combined with the bottom of the water filter cylinder, thereby increasing the sealing property of the sealing hammer body.
