•     Defined dilution of large droplets of factor 10
•     Proven dilution factor 10 and 100 for droplet sizes up to 7 μm
•     Easy connection with Promo® and welas® digital aerosol spectrometers
•     Internal pump for on-site operation
•     Insensitive to pressure fluctuations of ± 200 mbar
•     Simple handling
•     Robust, durable, low maintenance
•     Cost effective

Description

The dilution of large droplets is particularly important when measuring highly concentrated droplet aerosols. Since large droplets are difficult to dilute, standard systems only work up to a size of 1 – 2 μm The newly developed dilution system LDD 10 (dilution factor 10) is the first system to dilute almost loss-free large droplets up to 10 μm

The good dilution factor of large droplets was tested with monodisperse DEHS droplets (oil) of different sizes. The results for the sizes 5 μm and 7 μm are shown in Table 1.
