Electrochemical cells, HMOS / GSS, and UV. Electrochemical ozone sensor uses a porous membrane that allows ozone gas to diffuse 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 ...

Gas Sensors Ozone

Products without "active sampling" (electrochemical and conventional HMOS products) will normally underread ozone concentrations below 200 parts per billion and struggle with sensitivity and accuracy, particularly in low air flow. "Active sampling" requires air to be blown or pumped to the sensor under precise flow conditions. Aeroqual fan based monitors are designed to be held at right ...
