Automated Fisher number measurement with Sub-Sieve AutosizerBoosting the productivity of particle sizing via the air permeability technique
Norcross, GA, USA – 03 December 2019 Micromeritics Instrument Corp., a global leader in material characterization technology, today launched the new highly automated Sub-Sieve Autosizer II (SAS II), an instrument that boosts the productivity and accuracy of particle sizing via the air permeability technique, a benchmark in many industries. A direct and substantially improved successor to the renowned Fisher Model 95 SubSieve Sizer (FSSS), it generates ‘Fisher numbers’ which are highly consistent to those of its predecessor. With easy-to-use functionality and electronic data recording, the new SAS II is particularly useful for those complying with specific ASTM standards including E2980, E2651, B330-12 and B330-15 for metal powders and C721-15 for alumina and silica powders (ceramics).
The SAS II delivers particle size measurements in the range 0.2 to 75µm, a range that tends to be too fine for economic and/or accurate sizing by sieve analysis. It utilizes the non-destructive
