Sampling System for Atmospheric Aerosol Model - 3772200
Sampling from ambient air is not trivial. Conditions such as temperature, humidity, wind speeds and wind direction are variable. Furthermore, diffusion losses particularly from the smallest particles can significantly change measurement results.
The Technical Specification CEN*/TS 16976 aims at harmonizing the continuous measurement of particle number concentration in ambient air. It describes a standardized method not only for the Condensation Particle Counter (CPC), but also for its sampling and conditioning system.
