It is possible to directly measure the mass concentration of suspended particulate matter in the atmosphere.
The Piezo Balance Dust Meter MODEL 3521 uses a piezoelectric measurement method to directly measure the mass concentration of suspended particulate matter in the atmosphere. With a memory function, it is ideal for managing work environments. Due to its minimal influence from the physical properties of dust, it can measure in environments where the nature of the dust is not known in advance. 【Features】 ○ Displays mass concentration in real-time ○ Minimal influence from the physical properties of dust, allowing measurement in environments where the nature of the dust is not known in advance ○ Equipped with a memory function for transferring measurement data to a computer or printer ○ Comes with a convenient carrying case For more details, please contact us or download the catalog.
