New Development!

The newly developed High Dilution System HDS 561 is characterized by its very wide, variable range of dilution ratios. The volume flow rate setting is factory-provided and made custom-specific and can be adjusted in a very wide range. These features eliminate the need for cascading multiple dilution systems and reduces the system pressure loss. The possibility of remote checking and control of dilution ratio expands its application fields, as there are e.g. dilution of aerosols for measurement with particle counters, defined supply of a source strength with aerosol generators. The applied HEPA-filter system guaranties long lifetime and state of readiness.

Optical particle counters, e.g. the LAP 340, have a physical limit up to which concentration they work accurately. According to standard VDI 2083 for testing clean rooms and work benches it is compulsory to carry out measurements with increased concentrations in the incoming aerosol. For such tasks of measurement of high concentrated aerosol the newly developed variable dilution system HDS 561 is fitting best.
