Electrochemical ozone sensor and instrument with characterization of the electrode and gas flow effects

An electrochemical ozone sensor with a new sensing composite material has been developed. The ozone sensors exhibit a strong and stable response to ozone. The responses to flow velocity and concentration have been characterized in order to develop improved ozone sensing instrumentation. Nearly an order of magnitude change in response with flow velocity is noted, along with a leveling off of the change at both the maximum and minimum flows. Operating in these regions can allow more accurate and consistent measurements.
