welas digital system

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.

welas® digital technology allows unambiguous measurement of particle size on an individual particle, without dilution, also in the highest concentration up to 106 particles/cm3.
The patented optical fibre technology allows quasi-simultaneous measurement at two measurement points up to 100 m apart with one device and two sensors.

Unique in the world: The broad spectrum of easily exchangeable welas® aerosol sensors enables perfect matching of the measurement technology with the particle spectrum (120 nm to 100 µm) to be measured, the particle concentrations, the respective pressure and temperature ranges.

Calibration can be performed on-site independently by the customer!

This allows reliable and economical particle size and concentration analyses even in difficult environments.
