Description
The Palas cloud droplet analyzer for cloud aerosols is a high-resolution optical aerosol spectrometer optimized for measuring the size distribution and number concentration of cloud aerosols such as droplets and ice crystals. Using the latest optical light scattering technology single particles and high-resolution components such as droplets and ice crystals can be distinguished. The same optical sensor technology is also used in research applications from KIT for Ice Nucleation Studies at AIDA -Chamber. Additionally, the cloud water content as well as mean droplet diameter can be reported.

The Palas cloud droplet analyzer uses the recognized measurement technique of optical light scattering according to ISO 21501-1 on individual particles and is equipped with an LED light source of high light intensity, high light stability and long service life. It is equipped with a Sigma-2 sampling head in accordance with VDI 2119, which enables representative sampling even in strong winds. An automatically controlled heater on the sampling head prevents icing and thus enables reliable sampling even in adverse climatic conditions.
Palas also offer a wide range of aerosol spectrometers for varying applications, condensation particle counters, SMPS systems and other devices for air quality and other measurements.
