Ozone Leak Detection

Tech Tip.

Ozone Leak Detection is an inevitable part of operating any long term ozone system.  As with any toxic gas used for industrial and commercial applications eventually fittings, piping, and parts will eventually fail, allowing that toxic gas, in this case ozone, to leak.  What makes ozone slightly more challenging is the difficulty to measure ozone.  Ozone detectors have to measure a oxidant that is slowly destroying the very sensor intended for finding the ozone gas.  The short half life of ozone is also challenging.  Now it is there, later it is not.  Is there really a leak?

Tips for Measuring Ozone in an Occupied Room

Here are some helpful tips for finding ozone leaks:

Use a high quality ozone sensor.  To find an ozone leak use an ozone sensor that responds quickly to ozone.  We suggest the C-16, or the A-21ZX.  See information in hyper links for details.  Both of these sensors will react quickly to ozone, and can help pinpoint the ozone leak.  The C-16 uses a probe that can pinpoint exact location.  This is our personal favorite ozone sensor.

Turn down the ozone.  The ozone level in the room can quickly become dangerously high limiting your time in the room to find the ozone leak.  Try turning the ozone generator down to the lowest level to produce less ozone and give yourself more time.

Turn off the ozone.  It may be necessary to turn off the ozone all together.  Keep your feed-gas operational but turn off the ozone generator.  Use a bottle of soapy water, and some patience.  you will eventually find the gas leaking by seeing bubbles forming near the fitting or piping.

Use common sense.  If your still not winning the battle, step back and think this through.  Where will ozone most likely be leaking?  Are there any pipes or hoses that commonly have vibration or movement, these would be most likely to spring a leak.  Are there components or fittings that have recently been opened?  Concentrate your efforts on threaded fittings, and push type fittings.  These are most common leaks.


Most of all take your time and be patient.
