Guidelines on How to Measure Ozone
The following information is presented to help users operate their
Ozone Detector in the most effective and efficient manner.
General
• Ozone is heavier than air and tends to sink.
Thus detection of leaks from ozone generating equipment should be performed at
the most appropriate position.
• Ozone will react and decompose on surfaces such as walls,
furniture etc.
• Smell is not a reliable test for the presence or concentration of
ozone as the odour threshold varies widely between people and
is affected by local ambient conditions.
Permanent Controller Placement
• The Ozone Detector has been designed to measure
the ambient concentration of ozone.
The controller must not be placed directly in an ozone stream.
• For indoor local area monitoring attach the controller to an inert
surface with the inlet unobstructed.
• For leak detection mount the unit near the ozone equipment.
• Ensure that the controller is protected from excessive water
splashing, dust, vibration, excessive heat or cold, high
concentrations of ozone and excessive swings in humidity.
False Readings
• The Ozone Detector has been designed to respond
selectively to ozone, however other oxidizing gases such as
chlorine and nitrogen dioxide can generate false readings if they
are at high concentrations.
High concentrations of hydrocarbon gases such as vapours of alcohol,
oils and solvents can reduce and mask the concentration of ozone.
