How to Check Ozone Levels in Water

Water Applications

We are very excited to offer a new product on our website: SenSafe® Ozone Check Strips! Each bottle contains 50 strips for quick and effective testing of ozone levels in any water source.

Testing how much ozone is in your water is important! With SenSafe® Ozone Check Strips, you can accurately detect faint ozone levels in your water. This includes drinking water, fish tanks, and many more applications.


Easily detect ozone levels in your water source:

  • Dip the test strip into a water source (at least 50mL) for 10 seconds and gently move the strip back and forth
  • Shake briskly a couple times to remove excess water (do not dry completely)
  • Wait 20 seconds and then compare to the chart on the bottle for results. For best results, fold the strip in half to see the color result on a white background.
  • After the 20 second wait period, compare your results with the chart on the back of the bottle

    An explanation on the “importance” of knowing the amount of Ozone would be EXTREMELY helpful to this article. Thanks
