Kanomax Model 3521 is a unique respirable aerosol monitor, providing direct mass concentration of particulates using Piezobalance technology. Impactor is 10 µm, 4 µm.
Principle
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.
