201-2 What is a fisher sub sieve sizer

The fisher sub sieve sizer was first developed by American company called Fisher Scientific. The working principle of fisher sub sieve size is to use steady flow pump to drive dry air through the sample layer to measure the surface area of particles, and then calculate the average particle size by formula. One obvious advantage over other particle size analyzers even laser particle size analyzers, is that the results of particle size measurement can be directly read, which is very convenient and intuitive.
