Constant potential electrolytic gas sensor

Constant potential electrolysis sensor is the measure most widely used drug class field a technology leader in this area of foreign technology , so this type of sensor is mostly dependent on imports. Constant potential electrolysis gas sensor structure: in a plastic tub made ​​of a cylindrical body , the installation working electrode , a counter electrode and a reference electrode , an electrolyte is filled between the electrodes , made ​​of a porous PTFE membrane , the top of the package. Preamplifier connected to Cooling Temp Sensor electrodes , applied between the electrodes a certain potential, the sensor is in working condition. Gas and the working electrode electrolyte oxidation or reduction reaction occurs in the reduction or oxidation of the electrode reaction , the equilibrium potential of the electrode is changed , the change is proportional to the gas concentration value .
