YJJ ME4-SO2-E4 Electrochemical Sulfur Dioxide Gas Sensor For Urban Atmospheric Environment Monitoring

Product Description:

ME4-SO2-E4 Electrochemical Sulfur Dioxide Gas Sensor For Urban Atmospheric Environment Monitoring

Features:

ME4-SO2-E4 sensor is a constant potential electrolytic SO2 sensor. SO2 and O2 undergo corresponding REDOX reaction at the working electrode and the opposite electrode and release charge to form current. The concentration of SO2 is proportional to the current size. The concentration of SO2 can be determined by testing the current size. The sensor's fourth electrode auxiliary electrode is used to compensate the zero current, so that it has a strong signal level, low zero current characteristics.
