AIR QUALITY MONITOR The Kanomax 3521 Piezobalance Dust Meter weighs particulate mass concentrations which eliminates gravimetric sampling. Principles of Operation As the air samples enter into the system, they travel through an impactor which captures & removes the larger particulates from your sample. The smaller particulates then become electrically charged & deposited onto the piezo crystal. The total deposited particulate mass affects the frequency of the piezo crystal. Since the frequency change is proportional to particulate mass, an actual particulate weight is obtained.
