REQUIRED Technical/Functional Specifications - Adjustable Smoke Diluter. Capable of diluting a smoke stream up to a dilution factor of 500. A dilution factor should be adjustable from 1:10 to 1:500. The controller for the dilution factor should be digital and precise, with multiple dilution factor control up to 500. The equipment should be able to handle high-temperature smoke stream up to 500 Celsius. The equipment should be capable of avoiding smoke particle condensation during dilution. The equipment should be compatible to downstream cascade impactor or particle sizers at the diluted stream outlet and not interfering with the dilution factor. The equipment should be able to realize ISO-kinetic sampling of smoke particles from the main smoke stream. Accessories for the connection of the Cascade Impactor. Equipment should be portable. Installation should be straightforward and should not require modifications of existing smoke generation system and smoke tunnel. Installation should not require excess floor or countertop space. Equipment should be easily detached from smoke tunnel for cleaning and maintenance; REQUIRED Technical/Functional Specifications - Cascade Impactor. Capable of sampling smoke particles from a diluted or undiluted smoke stream. The equipment should be equipped with a vacuum pump that can be controlled to maintain sampling stream flowrate at variable pressures. The equipment should be able to handle elevated temperature smoke stream up to 50 Celsius. The equipment should be compatible to general stream dilution instrument at the diluted stream outlet and not interfering with the dilution factor. The equipment should be able to distinguish particle size ranges from PM10, to PM2.5, to PM0.1 in a gravimetric manner. Preferable that PM0.1 can be further distinguished into two to three sub-size range. Accessories for the connection of Adjustable Smoke Diluter. Equipment should be portable. Installation should be straightforward and should not require modifications of existing smoke generation system and smoke tunnel. Installation should not require excess floor or countertop space. Equipment should be easily detached from smoke tunnel for cleaning and maintenance.
