Aerosol Sensor welas® 2070

Aerosolsensor welas® 2070
Aerosol sensor with optical fibre technology for number concentrations up to 1,000,000 particles/cm3

The model 2070 aerosol sensors are equipped with a very small measurement volume and are used for coincidence-free measurement with a maximum number of concentrations up to 1,000,000 particles/cm3 and in the highest mass concentrations, e.g., Arizona dust A2, SAE Fine, up to 1,000 mg/m3. Measuring range: 0.2 – 10 µm / 0.3 – 17 µm / 0.6 – 40 µm.

Operation principle

Your special advantages

  • The sensors are easily replaceable
  • World's smallest and most robust sensors in the 2000 series
  • Very good agreement of all sensors regarding particle size and particle concentration
  • Minimization of particle losses in long sampling lines by easy installation of the sensor directly at the sampling point
  • Sensors for in-situ measurements
  • Measurement in explosive environments in 2000 series (without heating)
  • Easy to clean
  • Simple operation
  • Reliable function
  • Low maintenance
  • Reduces your operating costs
