- Model DDS 560 - Dynamic Dilution System


The Dynamic Dilution System DDS 560 is designed to definitely and reproducibly dilute aerosols according to EN ISO 14644 part 3 and VDI 3491 Blatt 15 with possibility to adjust the dilution factor. The adjusted dilution factor is shown on a display. On the basis of this principle particles are removed from the sample according to the chosen and displayed dilution ratio. The particle size distribution will remain unchanged. - Various adjustable dilution factors - Suitable for various operation flows (particle counter flows) - Monitoring the particle counter flow rate - Maintains gas characteristics of original aerosol - Closed system - no pressurized air necessary - For flow rate from 0.5 to 3 l/min - Dilution ratios from 1:10 up to 1:350
