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 model variant LDD 100 H can be heated up to 150 °C and thus prevents condensation.
The newly developed dilution system LDD 100 H (dilution factor 100) is the first system to dilute almost loss-free large droplets up to 10 μm
