Dekati® eDiluter™


Dekati® eDiluter™ is a portable dilution system that makes sample conditioning as easy as it can be. The Dekati® eDiluter™ comes standard with a fixed 1:60 dilution factor, but it can as well be provided with a customer specific dilution factor in the range of 1:25-1:225. The Dekati® eDiluter™ dilution parameters can be monitored on an integrated LCD display and a rotary controller knob allows the user to fine tune the dilution temperature. The high sample output of the Dekati® eDiluter™ allows the system to be fully integrated with all Dekati® Instruments and is also compatible with all other commercially available measurement instruments.

The operating principle of the Dekati® eDiluter™ is based on two-stage dilution. The first dilution stage is heated while the second diution stage operates at room temperature where the aerosol sample is also cooled in a controlled manner. Each dilution stage consists of an ejector diluter with additional sheath air flow. The use of a large ejector nozzle and sheath air reduced the need for cleaning, and also minimizes particle losses within the system.
