Aerosol sensor welas® 2300

Aerosolsensor welas® 2100
Aerosol sensor with optical fibre technology for number concentrations up to 40,000 particles/cm3

The model 2300 aerosol sensors are equipped with a very big measurement volume and are used for coincidence-free measurement with a maximum number concentrations up to 40,000 particles/cm3. These sensors are therefore suitable for indoor air measurements and for filter testing in accordance with EN779. Measuring range: 0.2 – 10 µm / 0.3 – 17 µm / 0.6 – 40 µm / 2 – 100 µm.
