product sheet SAG 440Benefits
- constant and reproducible dosing rate over a wide concentration range makes it suitable for several applications
- refillable during operation – ideal for long term tests
- optional remote control unit for manual or computer control
To generate a test aerosol a defined amount of test dust is put on the feeding belt, the dosing wheel adds a set quantity to the dust uptake nozzle from where it is forwarded pneumatically to the test duct. To avoid electrostatic effects it is possible to discharge the particles with the Bipolar Aerosol Neutralizer Unit EAN 581 from Topas.
