The welas ® digital technology allows the unambiguous measurement of the particle size at the single particle, without dilution, even in the highest concentrations up to 106 particles/cm3.

The welas ® digital 2000 is a flexible, powerful, and economical light-scattering spectrometer system that determines particle concentration and size precisely and reliably. Unique are up to four measuring ranges in only one device:

CH Technologies offers the WELAS and Promo families of products, manufactured by Palas GmbH. They are widely used in filter testing and other applications. Both utilize the proprietary technologies that distinguish Palas spectrometers as the preferred choice.

The welas® digital 1000 is a flexible, powerful and economical light-scattering spectrometer system, which determines particle concentration and size precisely and reliably. With the welas® digital 1000, particle sizes above 120 nm can be reliably measured, as the special high power xenon high pressure lamp with very high light

The welas ® digital 2000 aerosol sensors can measure particles in a range of 200 nm to 100 µm reliably and precisely in terms of size and associated concentration. The welas ® 2000 aerosol sensors are also connected to the control and analysis unit with a …

On account of the patented T-aperture technology and the fast digital signal processing, the optical aerosol spectrometers from Palas® are the only systems in the world without border zone error, with coincidence detection and with coincidence correction.

CH Technologies Welas and Promo 3000 Series are best suited when more than one measurement location is a necessity. Manufactured by Palas GmbH, these white light spectrometers feature the state-of-the-art particle counting algorithms found in all of our spectrometers and are executed with the high quality standards for which Palas is known.

The welas ® digital 1000 is a flexible, powerful and economical light-scattering spectrometer system, which determines particle concentration and size precisely and reliably.
