HMK-22 Fisher Sub Sieve Sizer is a lab analysis instrument used to measure the average particle size (fisher number) of powders. It consists of air pump, pressure regulator, drying tube, sample tube, pinion, reading chart, manometer and needle valve etc. Air pump generates stable air flow and such air flow goes through pressure regulator and dried by drying tube then passing through the testing area. Particle size decides passage of the air and the level height. Read the particle size directly from the reading chart. HMK-22 uses imported American needle valve that can control the air flow precisely. The pump works with small noise and output stable pressure. HMK Test FSSS is manufactured strictly according to international standard and both accuracy and repeatability conforms to international standards ASTM D10070.

•  Laser cutting rack and pinion moves up and down smoothly, ensures measurement accuracy
•  Ultra abrasion and ultra mute fisher steady flow pump ensure consistency of airflow output
•  American high precision needle valve controls the level precisely
• Rugged base block lives in long-term pressing powder without distortion
•  Sample pressure calibrator easily finds the optimum porosity of the powder measured
• Ultra-rigid quartz glass parts, not easy to break
• Ruby sub sieve sizer calibrator can be traced to international standards
•  Easy installation and operation
•  Fast reulsts and stable performance
• Porosity range is extended further to meet more requirements on various industries
• Repeatability and accuracy conforms to international standards
•  Measurement results are read directly without conversion
• Accurately measure average particle size of powder, as accuracy as 0.05 micrometer
•  Designed for powders with special properties that cannot be measured with other particle sizing methods
•  Gives the same results and agrees with all the historical data collected on the FSSS
