Overview
HMK-22 Fisher Sub-Sieve Sizer/Average Particle Size Analyzer (FSSS) uses air permeability to fast determine the average particle size of powders. It complete meets international standard ISO 10070 Metallic powders Determination of envelope-specific surface area from the measurements of the permeability to air of a powder bed under steady-state flow conditions and ASTM B 330 Standard Test Method for Fisher Number of Metal Powders and Related Compounds. HMK-22 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, etc.
