SWPS

Model 1090—Electrical Ionizer

For charge conditioning to generate a Boltzmann equilibrium charge on aerosol particles without radioactivity.
High accurate charge conditioning for aerosol concentration and size distribution measurement by electrical mobility

Model 1000-WPS

Combines laser light scattering, differential mobility analysis, and condensation particle counting to automatically count and size aerosol particles from 10nm to 10,000nm (0.01μm to 10μm) in up to 120 particle-size channels
