Aerosol Spectrometers

The success of the Palas® aerosol spectrometers is based on the development by the University of Karlsruhe, KIT of a measurement method using a white light source, 90° scattered-light detections and an optically defined measurement volume. It is still the world's only optical measurement method that ensures precise particle and concentration determination over a wide measuring range up to 100000 particles/cc. In 2008 the development was commercialised as the welas® digital system (White Light Aerosol spectrometer System) with patented T-aperture technology. Patented optical fibre technology allows reliable quasi-simultaneous measurement at two measurement points with one device and in chemically aggressive gases. Palas® offers with the model groups welas® digital, Inas®, Promo® and Fidas® the most modern, reliable and scientifically most thoroughly investigated optical aerosol spectrometers in the world. Palas combines the measurement technology with measurement and analysis software for easy data handling via internal touchscreen or attached PC with many setting and display features, e.g. setting of refractive index. Coding for automatic filter testing with Palas® test rigs and FTControl software allows integration into process control units external control, e.g. via modbus.
