Gas analyzer T265

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. An inexpensive external cylinder of NO provides over one year of reagent for the T265. A unique AutoZero feature provides superb stability by continuously correcting for zero drift, while advanced Adaptive Filtering allows the analyzer to optimize performance under changing conditions. Optional zero and span valves allow automatic, unattended calibration checks. All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.
