Description

For checking airborne particle counts and sizes in rooms and ventilation systems. Provides six size channels and result storage. Monitors six particle-size channels simultaneously, with cumulative and differential counting, data logging and USB/Ethernet transfer. An isokinetic probe supports cleanroom and ventilation surveys. Battery life depends on mode; continuous sampling typically reduces runtime to 5 h.
