Chemiluminescence 03 Analyzer
Model T265
-
Teledyne Advanced Pollution Instrumentation
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 Chemilumescence with Nitric Oxide (NO) as a reagent, making is 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, turpines, 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.
