T400 - O3 Analyzer    Get Quote

The Model T400 UV Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in ambient air. A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically, a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone measurement.
Ranges: 0-100 ppb, 0-1000 ppb.  Learn More

T265 - O₃ Analyzer    Get Quote

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.
Ranges: 0-100 ppb to 0-2,000 ppb.  Learn More

480H - Process Ozone Monitor    Get Quote

The Model 480H is a state-of-the-art high concentration ozone monitor. The 480H provides accurate and stable readings over long time periods and was designed with the user in mind. The modular design allows for easier field serviceability. The Model 480H is housed in a splash-proof NEMA 4X wall mount enclosure. The sensor module contained in the Model 480H uses detectors with a very narrow band of spectral sensitivity, eliminating the need for UV band pass filters which are subject to deterioration by UV or humidity. Two detectors are used: one for the ozone measurement, and the other to compensate for changes in UV source intensity.

452 - Process Ozone Sensor    Get Quote

The Model 452 is a microprocessor based gas sensor for measuring high concentrations of ozone in oxygen or air with accuracy and dependability. The measurement principle is based on the absorption of UV light at 254nm. Readings are available in % by weight, or grams/Normal cubic meter. Temperature and pressure compensation up to 3 Bar Absolute is a standard feature.
Ranges: 0-5% to 0-20% w/w  Learn More

454 - Process Ozone Monitor    Get Quote

The Model 454 is a microprocessor based gas monitor for measuring mid to high concentrations of ozone in oxygen or air. Available in a standard DIN panel mount configuration with a 4-digit LED display, the compact design provides ease of mounting and installation. The measurement principle is based on the absorption of UV light at 254nm. As the sample containing ozone flows through the absorption cell, it is exposed to UV light at the 254nm wavelength. The amount of absorption by ozone is measured by a narrow bandwidth UV detector.
Ranges: 0-5% w/w to 0-25% w/w, 0-100 g/Nm³ to 0-500 g/Nm³  Learn More
