Fine dust monitor Fidas®

The Fidas® series uses the recognized measurement technology of optical light scattering of single particles and is equipped with a white LED light source with highly stable output and long lifetime. The patented T-aperture technology and digital signal processing guarantee optimally accurate particle measurement, even at high concentrations. In addition to PM values, the particle size distribution can be activated in 32 size classes per decade within the particle size range of 0.18 – 18 µm and used for additional assessments. The Fidas® series can be optionally equipped with a Sigma-2 sampling head as per VDI 2119-4 or measuring heads for PM2.5 or PM10. A drying system (intelligent aerosol drying system – IADS) prevents measurement inaccuracies caused by condensation effects resulting from high humidity. These devices have been successfully used worldwide based on these advantages.
– Useful combination of the Fidas® and U-SMPS systems for particle measurements in the size range of 8 nm to 40 µm
