Measuring Principle

UV absorption Ozone analyser is developed based on Beer-Lambert technology, It is applied to monitor concentrations O3 in ambient air. 254 mm UV light passes through sample cell and absorbed by ozone inside it. Absorption value has certain ration with O3 concentration.

 

By cyclically 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 analyser can completely control all functions and also provide online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement.
