Aerosol sensors welas® 2000 system

The welas® digital 2000 aerosol sensors can measure particles in a range 200 nm to 100 µm reliably and precisely in terms of their 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. The small and robust aerosol sensors can therefore be installed very flexibly near the sampling location.The size of measurement volume 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 therefore a good statistical confidence level in various concentration ranges.The welas® 2000 series of aerosol sensors offers the biggest selection of sensors for diverse application areas in terms of particle concentration, temperature and pressure range.
