The Aerosol Particle Mass Analyzer Model APM 3601 is manufactured by Kanomax USA, and classifies particle by mass based on the balance between centrifugal force and electrostatic force. It is a desktop and lightweight unit with an APM-II feature that classifies aerosol particles of 0.01 to 100 femtograms.
The instrument's control function can adjust the rotation speed and applied voltage, while its display function shows the applied voltage, rotation speed, and differential pressure b/w inlet and outlet. The Model APM 3601 is engineered for use in mass distribution measurements, particle density research, and other applications.
