Palas Fidas® 200 E

Dust aerosol spectrometer

The Palas Fidas® 200 E is an EN 16450 approved fine dust aerosol spectrometer for simultaneous measurement of PM2.5 and PM10. At the same time, PM1, PM4, PMtot, the particle number concentration and the particle size distribution are calculated and recorded. It features a separate sensor module to allow for flexible installations in stations with existing ceiling glands.

Acoem Australasia (Ecotech Pty Ltd) is the official distributor of Palas in Australia and New Zealand.

  • Regulatory pollution control in monitoring networks
  • Ambient air monitoring campaigns
  • Long-term studies
  • Emission source attribution
  • Emission dispersion studies (eg fires, volcanoes)


Palas® has developed the certified devices in the Fidas® 200 series for environmental monitoring in networks, immission measurements, long-term studies, emission source allocation or propagation studies, for example at volcanic eruptions or large-scale fires. The system is used just as successfully in public measuring networks and conurbations as it is along coasts, in mountains, in the Arctic and in desert regions.

Fine Dust Monitoring systems

Fidas® 200, Fidas® 200 S and Fidas® 200 E are currently the world’s only optical fine dust measurement systems with single particle analysis for the fine dust fractions PM10 and PM2.5 that have passed this test in accordance with DIN EN 12341 and DIN EN 14907 and have been certified in accordance with DIN EN 15267-1 & -2. The Fidas® 200 series has also been approved for regulatory measurements in the UK (MCERTS) and France (Homologation).
