ZWIN-AQMS-300 O3 Analyzer
Overview
Ozone analyzer adopts ultraviolet spectrometry principle and combines with advanced microprocessor technology.It provides accurate and reliable detection of O3 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 O3 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 O3 concentration.By cyelically alternating of magnetic valve and measuring sample gas and the sample without O3,the true and reliable measured concentration of ozone is obtained at last.
This analyer 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.
