MODEL 3521 / 3522 PIEZOBALANCE DUST MONITOR
3521 / 3522 FEATURES
The Kanomax PIEZOBALANCE Dust Monitor 3521/3522 is a unique respirable aerosol monitor, providing direct mass concentration of particulates using PIEZOBALANCE technology; ideal especially for oil mist monitoring.Read more
The Kanomax 3521 is equipped with 4 and 10µm impactors while the 3522 is equipped with a 2.5µm impactor.
Unlike conventional dust meters, which count particles, a PIEZOBALANCE dust meter like the 3521 or 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-crystal’s frequency.
Since the change in frequency is proportional to the mass of the particulates, the actual weight of the particulates is obtained.

A dust monitor measures the mass concentration of particulates in the air. This is typically expressed in milligrams of particulates per cubic meter of air. This makes the dust monitor very useful for monitoring substances that could negatively impact a person’s health.
We have two different types: a light-scattering monitor model 3443 (the industry standard) and a piezobalance monitor model 3521.
There are two key differences between the units. The first is that the light scattering model 3443 requires a K-factor to accurately report the mass concentration of particulates, while the piezobalance model 3521 does not. The second key difference is that model 3443 is suitable for long-term monitoring while the piezobalance model 3521 needs to be cleaned every hour to function correctly. The piezobalance monitor is also capable of measuring oil mist for specialized applications.
In order to accurately report on the mass concentration of particulates that it has measured a light-scattering particle counter needs to know the density of the particulates at the measuring site. Without this the unit will still count particulates, but it cannot accurately gauge the concentration in the air. To obtain the factor it is necessary to obtain a gravimetric sampling of the particulates at the measurement site. This is done by collecting particulates in a special sample container and then sending it to a lab for analysis.
Yes, all our instruments come with a calibration certificate.
Annual calibration is recommended to ensure accuracy. However, this can vary based on how often the dust monitor is used and the environments it’s used it. Also, some companies have an SOP in place that specifies how often the instrument will need to be serviced. More specifically, regulatory compliances may dictate the calibration interval.
