AIR QUALITY MONITOR The Kanomax 3521 & 3522 dust monitors utilize piezobalance technology for real-time measurements of dust concentration. Featuring easy set up and operation, the 3521 and 3522 are perfect choices for a wide range of applications including IAQ investigations, industrial hygiene, occupational health & safety, product quality control, and laboratory research. As air sample enters the system, it travels through the impactor, which captures and removes larger particulates away from the sample. Smaller particulates become electrically charged and deposited on the piezo-crystal. The total mass of the deposited particulates affects the piezo-crystal’ s frequency. Since the change in frequency is proportional to the mass of the particulates, the actual weight of the particulates is obtained.
