The 14697 O3 Scrubber Assembly is the official zero air scrubber spare part for the Thermo Scientific Model 49i UV Photometric Ozone Analyzer, widely used in EPA ambient air quality monitoring stations.

This scrubber assembly catalytically decomposes ozone from incoming zero air, eliminating O3 interference and providing clean zero gas for instrument zero calibration and baseline stabilization. It is a mandatory annual consumable for Model 49i maintenance to prevent baseline drift, measurement bias and noisy ozone
