Ozone analyzer adopts ultraviolet spectrometry principle and combines with advanced microprocessor technology. It provides accurate and reliable detection of 03 at ppb^ppm level to meet the requirement of ambient gas monitoring. UV adsorption Ozone analyzer is developed based on Beer-Lambert technology. It is applied to monitor low concentration 03 in ambient air. 254nm UV light passes through sample gas cell and is absorbed by ozone inside it. Adsorption value has a certain ration with 03 concentration. By cyclically alternating of magnetic valve and measuring sample gas and the sample without 03. the true and reliable measured concentration of ozone is obtained at last. This analyzer can completely control all functions and also provides online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement.
