What Are Ozone Monitors, and How Do They Work ...

· Electrochemical Ozone Sensors. These sensors use electrolytes and electrodes to measure ozone presence. When ozone comes into contact with the electrolytes in the device, it interacts with electrolytes. This causes electrons to start passing between the two electrodes, triggering the device. This type of sensor works quickly. In just a few seconds, it will analyze the atmosphere around it and …

Ozone detection in the ppb range with work function ...

Thin evaporated films of potassium iodide (KI) are highly sensitive to ozone in work function measurements. Among various other materials KI is well suited for limit detection in the ppb range in normal humid air with work function sensors like SGFET. The cross-sensitivities to other oxidants are comparatively small which is due to a redox system of highly oxidated states on the layer surface ...

Ozone sensor operating according to the work function ...

An ozone sensor has an ozone-sensitive layer containing an ozone-sensitive material which is encapsulated in a polymer or in a polymer mixture or is coated by at least one polymer or polymer mixture. Advantages result from a longer service life of the ozone-sensitive materials which, because of their high hygroscopic properties, would not be stable without encapsulation or coating. Furthermore ...

Abstract Indium oxide thin films were deposited on silicon substrates for work function sensing as well as on alumina (Pt) conductivity sensors. A correlation of work function and conductivity measurements due to ozone in dry and humid air reveal that a chemisorption state dominates both sensor effects at temperatures below 200°C. The influence of humidity is found to be comparatively small ...
