The Model T265 is the only commercially available US EPA Federal Reference Method for Ambient Ozone Monitoring according to the latest US EPA regulatory rules for O₃. The instrument uses Chemiluminescence with Nitric Oxide (NO) as a reagent, making it safe, stable, and effective for all applications. The NO-CL method for Ozone has several advantages over the conventional UV absorption technology, including the avoidance of positive and commonly found interferrents such as VOCs, fine particulates, Mercury, terpenes, ClO₂ and others. If these pollutants are present in the atmosphere, it can cause UV absorption analyzers to give an artificially high ozone measurement. The innovative T265 combines speed of response, sensitivity and stability of our proven nitrogen oxide analyzer, with a simple user interface, to provide reliable ozone measurements under the harshest conditions.

The Model T400 UV Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in ambient air.

The Model T802 O₂ analyzer uses the proven paramagnetic measurement principle, coupled with state of the art microprocessor technology, to provide accurate and dependable measurements of Percent-Level O₂. The Model T802 can also be equipped with an optional CO₂ sensor, using the robust non-dispersed infrared (NDIR) measurement principle.
