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

features
- direct measurement of aerosol mass by kanomax unique piezobalance method
- precise. no need to compensate readings regardless of particle character
- zeroing not needed
- se-lectable run duration (24s or 120s)
- built-in cleaning mechanism for easy maintenance of piezobalance transducer
- calculation of aerosol mass concentration from cpm
- powered by built-in ni-cd battery or ac adapter
- while conventional dust meters "count" particulates, the piezobalance dust meter "weighs" mass concentration of particulates.
- data can be reviewed on-screen, printed or downloaded to a computer.
- software included for easy data download and processing.
- easy operation requires no special training
