Software for particle and concentration analysis with welas®digital and Promo®aerosol spectrometers

The PDControl software is designed for measurement value acquisition and data analysis by all the welas® digital and Promo® systems. It enables quick and easy particle size and concentration analysis.

The PDControl software provides special advantages for analyzing rapid changes in concentration and particle size distributions using the high time resolution of 10 ms, depending on the measurement system. In addition, PDControl enables the transparent display of measured distributions with analysis of the coincidence percentage, as per Dr. Umhauer and Prof. Sachweh (see last figure). Palas® software solutions in particle measurement technology, filter testing, and test rig control are based on our many years of experience. They have been continuously optimized and further developed in close collaboration with our international customers based on their requirements. As a result, Palas® software is efficient and provides many advantages in daily applications.

Operation principle
