The Spa Ozone Detection Kit is our home spa ozonator tester — the reliable method for testing if a hot tub ozone generator (even if making air bubbles) is producing effective ozone. Research shows that up to 60% of home spa ozonators are generating insufficient ozone, or none at all! Our simple ozone detection kit indicates if your spa ozonator needs replacement.
