Freeness Tester

Measurement range 0~100 ° SR, measuringflask Graduation 1 ° SR, test distillation water temperature 20 +/- 0.5 ℃, test distillation water volume 1000ml, discharge time 149 +/- 1s

Pneumatic beating degree Tester, also known as knockout degree Tester, is a special instrument for measuring the performance of pulp water filtration. It is a laboratory routine test instrument designed according to the principle of Shobar-Riegler method.

Specially designed for all kinds of pulp suspensions not greater than 100 ° SR, Measurement range 0~100 ° SR, cone rise speed 100 +/- 10mm/s, overflow discharge time 149 +/- 1s, remaining volume 7.5~ 8.0ml

Dedicated to measuring the degree of beating of the pulp (ie, the degree of knockout). Measurement range of 0~100 ° SR with high-precision Graduation interval (1 ° SR) by measurement of diluted pulp suspension, and ensure that the overflow port discharge time is 149 +/- 1 seconds, and the cone rise speed is 100 +/- 10mm/s

The measurement of diluted pulp suspended water rate was carried out by Schopperr-Riegler test method, with a range of 1~ 100SR, which conforms to ISO, GB/T, QB/T standards.

Used for measurement of water filtration rate of diluted pulp suspensions, it features an adjustment mechanism, a design of manual compression sealing vertebrae, and a three-legged leveling mechanism to ensure good sealing between the sealing vertebrae and the cylinder. The instrument is suitable for quality control of diluted pulp and laboratory research.
