Ozone Analyzer Working Principle - Inst Tools

Ozone measurement. Ozone (O3) is an instable molecule of three oxygen atoms and a very strong oxidizing agent. At room temperature it is a gas. Due to its instability it cannot be stored in pressurised cylinders and has to be prepared on site. O3 is an eco-friendly disinfectant. However, its great disinfection strength can only be used to good advantage in suitable reactors with a reaction time of at least 3 minutes. The long-term effect of O3 …
