Aerosol sensors welas® 2000 System

Aerosolsensor welas® 2070

Aerosol sensors for the welas® digital 2000 / 3000 and Promo® 2000 / 3000 aerosol spectrometers

Aerosol sensor with optical fibre technology for number concentrations up to 1,000,000 particles/cm3
Aerosol sensor with optical fibre technology for number concentrations up to 500,000 particles/cm3
Aerosol sensor with optical fibre technology for number concentrations up to 40,000 particles/cm3
Aerosol sensor with optical fibre technology for number concentrations up to 4,000 particles/cm3

The welas® digital 2000 aerosol sensors can measure particles in a range of 200 nm to 100 µm reliably and precisely in terms of size and associated concentration.

The welas® 2000 aerosol sensors are also connected to the control and analysis unit with a fiber-optic cable of up to 50 m in length. Therefore, the small and robust aerosol sensors can be installed flexibly near the sampling location.

The measurement volume size is crucial for coincidence-free particle size and particle number measurement. The welas® aerosol sensors are equipped with various sizes of measurement volumes and can therefore be optimized for particular particle concentrations for coincidence-free measurement. This offers the advantage of a high particle rate and an excellent statistical confidence level in various concentration ranges.

The welas® 2000 series of aerosol sensors offers the most extensive selection of sensors for diverse application areas regarding particle concentration, temperature, and pressure range.
