welas® digital 3000

Aerosol spectrometer with two aerosol sensors, highest particle size resolution, measuring range from 200 nm to 100 µm for quasi simultaneous measurements

The welas® digital 3000 is a flexible, powerful, and economic light-scattering spectrometer system with two aerosol sensors, which determines particle concentration and size precisely and reliably.

Unique are up to four measuring ranges in only one device:

  • 0.2 µm – 10 µm
  • 0.3 µm – 17 µm
  • 0.6 µm – 40 µm
  • 2 µm – 100 µm (additionally for sensors 2300 and 2500)

welas® digital 3000 is famous for up to 128 size channels per measuring range and a concentration range from < 1 particle/cm3 to 106 particles/cm3.
