Ambient Ozone Monitors
Ozone leaks around an ozone generator or the associated equipment can create a safety hazard for operators of the
equipment. While ozone can be detected at concentrations well below those that are considered dangerous, it is a good
idea to have at least one ambient ozone monitor.
These unit will have th option for alerting the operator to low level leaks with an indicator light or audible alarm and at
higher levels will shut down the ozone generator. There are two types: UV photometers and electrochemical sensors.
The UV photometer type draws a sample of the ambient air into the unit where UV light is past through the gas sample.
UV at the wavelength used does not "see" air or oxygen, but does measure ozone. While such monitors can measure a
range of concentration, measurements in the 0-1 ppm range would be the most common with a resolution of 0.001 ppm.
The other technology employs an electrochemical sensor that measure the reaction of ozone that passes through a
membrane and contacts a special electrode. The electrochemical sensors are available in ranges similar to the UV
monitors, but are somewhat less expensive. They are some what less accurate (+/- 5%). In the case of an ambient
monitor such accuracy is probably not important. Both sensor types are widely deployed in ozone water treatment
applications.
It is important to note that ozone is heavier than air, so ozone will tend to collect in low lying areas. Sensors should be
placed closer to the floor or in basement areas below the ozone generators or associated equipment. Hand held
versions of ambient ozone monitors can be used as personal warning systems or for locating leaks in an ozone water
treatment system.
