PMI Dilution Probe

PMI Dilution Probe for in-situ sampling conditioning of stack gases. The Dilution Probe performs four critical functions to prepare the sample from the stack or process, so it can be measured accurately and precisely by the analyzer. The probe uses an air-driven aspirator which extracts the sample from the stack or process. It is then passed consecutively through coarse and fine particulate filters, a pre-selected glass or metal critical orifice, and finally diluted with the air from the aspirator. This process has now reduced the dew point of the sample to below that of the ambient air, preparing the sample so that it can be transported via an unheated line to the analyzer up to 300 feet away.
