The Portable Test Aerosol Generator 3073 is an atomizer-type aerosol generator with a submerged two-stream nozzle. It generates particle concentrations from 102 /cm3 to >107 /cm3 and offers an adjustable flow rate from 0.3 to 4.5 L/min. A long-life, low-noise brushless swing piston pump provides pressurized air. The flow rate is set on the display and controlled with a nozzle pressure sensor and proportional valve. Solutions can be pre-mixed in a standard 100 mL laboratory glass bottle with DIN thread and quickly exchanged. When using it with an optional user-supplied battery pack, it can run for up to several hours depending on pack capacity and operation conditions.
