What are you testing for exactly? The mere presence of ozone gas, as in trioxygen/O3?

The presence of ozone may be ascertained by its smell, and by the fact that it liberates iodine from potassium iodide KI. A solution of potassium iodide is added to a few grains of starch dissolved in water, and in this paper is soaked, which then forms ozone test paper, which turns blue when exposed to ozone or ozonised air. The ozone liberates iodine from the potassium iodide, and the starch combines with the liberated iodine, forming a blue compound.

      Ozone Sensors  Bookmark   

Im sure one can buy ozone sensors.

You could also use a sacrificial alkene as a test subject as the ozone makes the olefin undergo ozonolysis to the carbonyl compounds which could be verified easily, because you would know what the alkene, and hence the carbonyl compounds, would be.

The reason I need to detect ozone is to detect the completion of ozone absorbtion in styrene dimer, see Post 320196 (Elementary: "Styrene > Hydratropic Aldehyde", Novel Discourse)

Maybe the smell of ozone will be good enough
