Continuous In-Situ sample extraction using our dilution system offers many advantages over In-Situ monitors and other extractive techniques.
Product Detail
Description:
The Model 797 Dilution System performs four critical functions to prepare the sample from the stack, so that it can be measured accurately and precisely by the analyzer. The system uses an air driven aspirator which extracts the sample from the stack. it is then passed conseculatively through a coarse and fine particulate filter, a preselected glass or quartz critical orifice and diluted with the air from the aspirator. This process has now reduced the dew point of the stack sample to below that of the ambient air.
Low cost installation, maintenance and operation
Low extractive flow rates, promotes loong filter life
No need for heated sample line in most cases
Diluted sample is transported at positive pressure
No moving parts anywhere in the system
Can be used in explosion proof areas
Easy dynamic in-situ calibration at total dilution system
Can be used with any exisiting ambient air analyzer
Manual or optional automatic blow back, backflushes coarse filter
Optional probe heater
Available in several corrosion resistant materials
