201-32 What is the optimum porosity of a Fisher sub sieve sizer?
It is necessary to press the powder sample to the specified height when using a fisher sub sieve sizer to test the particle size. This compaction is not random, but is based on the optimum porosity of the material.HMK-22 Fisher sub sieve sizer and spare parts.
HMK-22 Fisher Sub Sieve Sizer/Average Particle Size Analyzer (FSSS) is an optimal tool for subsieve particle size analysis and has become the best successor of discontinued Fisher Scientific Sub-Sieve Sizer (FSSS) Fisher Model 95 (Model 14-311A and older Model 14-311 Sub-Sieve Sizer). It uses Air Permeability Principle to fast and accurately measure the Average Particle Size i.e. Fisher Number FSSS of powders. HMK-22 Fisher Sub-Sieve Sizer completely meets international standards about fisher sub sieve sizers ASTM B 330 Standard Test Method for Fisher Number (FSSS) of Metal Powders and Related Compounds and 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. HMK-22 Fisher Sub-Sieve Sizer meets the urgent requirement of the industry to find a quality successor to particle sizing technique by air permeability device such as fisher model 95. It gives operators completely same test experience and the results agrees completely with all the tested data obtained by a Fisher Scientific Sub-Sieve Sizer Model 95.
