DS4-SO2-100 Solid-state Polymer Electrochemical Sulfur Dioxide Sensor
Basic Information:
Working Principle:
Adopting a three-electrode design, it utilizes solid-state polymer electrochemical technology. The sensor mainly consists of a working electrode, counter electrode, reference electrode, and solid-state electrolyte. SO₂ gas reaches the working electrode of the sensor through diffusion holes, where an electrochemical oxidation or reduction reaction occurs on the porous micro-surface of the electrode. Protons generated by the reaction migrate to the counter electrode through the polymer electrolyte, producing a current signal proportional to the concentration of the measured gas.
