201-1 What are the advantages and disadvantages of fisher sub sieve sizer?

The fisher sub sieve sizer is an internationally recognized method to measure the average particle size of powders. Compared with other particle size measurement methods, fisher method has its unique advantages.

• The most basic advantage is that there are already a large number of users of HMKTest fisher sub sieve sizer in the international and domestic markets, which makes the measurement values of users newly purchased instruments can be immediately accepted and recognized by the industry.
• The characteristics of the fisher sub sieve sizer are low cost, high performance and high stability.
• Compared with other particle size analysis methods, fisher method won’t meet the problem that sample agglomeration cannot be dispersed, especially for magnetic materials. Even the most advanced laser particle size meter can do nothing with it. Because the requirements of the laser particle size meter on dispersion effect is very high. Otherwise cannot measure accurately. Even if do the measurement, but the repeatability is too bad to apply. In terms of the fisher sub sieve sizer, we don’t need to worry about the problem of sample dispersion.
• The other advantage is about the dispersion problem. For example, cemented carbides are relatively large, easy to disperse, but also easy to settle, which lead to severe deviation of the measurement results. But far from worrying about dispersion, the fisher sub sieve sizer tests after compaction. This solves the users’ worries.
• However, due to the principle of measurement, fisher method can only give the average particle size value, rather than the particle size distribution value. The quantitative fast filter paper is used in the testing process of fisher sub sieve sizer.
