Beschreibung
Zusammenfassung:	An ozone detection system includes a source of sample gas containing a concentration of ozone. The system further includes a first airflow passageway for receiving a first sample of gas from the source. The first airflow passageway includes a catalytic scrubber to reduce ozone content in the sample gas and a second airflow passageway receives a second sample of gas from the source. A third airflow passageway results from the convergence of the first and second airflow passageways wherein the reduced sample gas and the unaltered sample gas are combined to form a diluted sample gas. A sensor is provided for sensing the ozone concentration in the diluted sample gas received from the third airflow passageway. A processor is provided operative to calculate the actual concentration of ozone in the sample gas as a function of the sensed concentration of the diluted sample.
