Abstract
A system for measuring optical extinction includes an optical cell having an optical cavity, a sampling fan, a duct system having an interior, and a controller. The sampling fan is associated with a sample outlet of the optical cell, while the interior of the duct system is in fluid communication with an optical cavity of the optical cell. The duct system includes an unfiltered inlet and a filtered inlet with an inline duct fan arranged to draw a sample from a sample source and force the sample through a filter into the interior of the duct system. The controller is configured to cycle the inline duct fan on and off while the sampling fan is continuously on to thereby cycle filtered samples and unfiltered samples through the optical cavity. Continuous operation of the sampling fan provides the same airflow conditions through the optical cavity for both filtered and unfiltered samples.
