Subsieve AutoSizer (SAS) - Powder Sizing by Air-Permeability

The HEL SAS is a new entry to the established field of air-permeability particle sizing systems. It has been developed as a direct and improved successor to the widely used Fisher Model 95 Sub-Sieve Sizer (FSSS). HEL have improved on the FSSS's performance and brought the technology to the 21st century by offering easy to use automated functions together with electronically recorded data.

The SAS is designed to - and succesfully does - generate "Fisher number" results identical to that of its predecessor (the Fisher FSSS). It is not intended to be "better" or "more accurate" - its objective is to produce the same values. This is a crucial point as the FSSS is still used as a benchmark in many industries and historical data going back decades exists for comparison purposes.
