Guidelines on How to Measure Ozone

The following information is presented to help users operate their Kanomax Gasmaster with an ozone
sensor installed 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 Kanomax Ozone Controller 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 Kanomax Ozone Controller 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.
