semiconductor sensor for ozone

What''s best for measuring ozone, electrochemical sensors ...

20160908· Electrochemical ozone sensors. In an electrochemical (EC) sensor, ozone gas diffuses across a porous membrane into a cell containing electrolyte and electrodes. When ozone comes into contact with the electrolyte, a change in electrochemical potential occurs between the electrodes causing electrons to flow. In zero air, little or no electron flow occurs. As the presence of ozone increases, the ...
