The 454 series is available in full scale ranges from 0-5% w/w to 0-25% w/w, 0-100 g/Nm3 to 0-500 g/Nm3, and is factory calibrated in accordance with International Ozone Association standards. 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.
A reference detector measures the lamp output to compensate for changes in light intensity. This method, using a narrow spectrum UV source and a narrow bandwidth detector, provides excellent performance and stability without requiring additional UV filters.
The 454 series includes temperature and pressure compensations that produce measurements which are normalized to standard conditions. A front panel keypad displays concentration or cell pressure, while LEDs indicate monitoring status. The units employ a state-of-the-art microprocessor design to provide accurate, dependable monitoring of the ozone process.
