ABSTRACT
HMK-22 Fisher Sub-sieve Sizer uses air permeability method for determining surface area to determine the average particle size of particles.
OVERVIEW
HMK-22 uses air permeability to fast determine the average particle size of powders. It is also named Fisher sub-sieve sizer (FSSS)/Average particle size analyzer. It is a necessary testing method in productions and research fields such as magnetic materials, powder metallurgy, refractory metal, special ceramics, tungsten materials, hard metal, nonferrous metal, nonmetal, chemical industries, building materials, national defense function material, ect.
