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.

The Kanomax 3521 is equipped with 4 and 10m impactors while the 3522 is equipped with a 2.5m impactor. Unlike conventional dust meters which count particles, piezobalance dust meter like the 3521 and 3522 weighs mass concentration of particulates. As an 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-crystals frequency. Since the change in frequency is proportional to the mass of the particulates, the actual weight of the particulates is obtained.
The Kanomax 3521 and 3522 have measuring ranges of 0.02-10mg/m3 with an accuracy of 10% of reading 1 digit (0 to 5 mg/m3) or 20% of reading 1 digit (5 to 10 mg/m3). The sampling flow rate is one liter/min. Data can be reviewed on-screen via a backlit display that is easy to read in poor lighting conditions. Data can also be transferred to a computer via an RS232C port. An optional printer is available for creating immediate record of test results. The meters can data log up to 500 readings. The included software makes it easy to download and process data.
