The Process Aerosol Monitor PAM 510 was developed for realtime measurement of the parameters mean particle size and particle number concentration. The instrument can directly be connected to the outlet of the SLG 270.
The system is also suitable for instrument calibration and aerosol research.
- simultaneous characterisation of particle number concentration and mean particle size
- determination of particle number concentration is independent from refractive index of the aerosol particles
- compact and robust design
- wide working range
- monitoring of aerosols
- monitoring of aerosol generators
Particles of a highly concentrated aerosol streaming through a measuring cell where a light beam is crossed, cause light extinction. By measuring of average transmission and their fluctuation, the particle number concentration can be calculated independendly of the refractive index of the aerosol material to be analysed. Is the refractive index known, the average particle size can be computed simultaneously.
