Ozone Sensor

Smell is not a reliable test for the presence or concentration of ozone.  Ozone has a sweet smell, but the odor threshold varies widely by the person and the ambient conditions.

Ozone sensors are widely used to monitor workplace ozone levels.  Sensors are also used to measure ozone given off by processes such as electric power generation and plastic film treatment.

The allowable concentration of ozone in the workplace usually ranges from .05 to .10 ppm depending on the time of exposure and the regulatory agency involved.
