The Dekati® High Pressure Diluter DEED-300 is a two-stage dilution device for taking aerosol sample from high sample pressure such as pre-DPF conditions. The DEED-300 is designed especially for these conditions and it always keeps a constant dilution factor regardless of the sample pressure inside the tailpipe.
Total dilution factor in the DEED-300 unit is typically between 40 and 60 and it is individually calibrated for each unit for optimal results.
