Indicator Circuit for Ozone Production

[Rey25]

Dear Friends,
I am trying to purify water using corona effect. I have a high voltage 30KV transformer to ozoneate the water in a tube, and it works. I need to add an indicator to verify that there is ozone being produced. Can anyone help me with a simple go-no-go circuit?
Thanks
Rey

Commercially available Ozone Meters - Detect ozone in air and dissolved in water.. Did you need to build your own?

Yes, an ozone detector is commercially availble, and I know my system works. I only need to add an indicator to verify that there is ozone being produced. I am looking for a simple go-no-go circuit.
Thanks
