YJJ ME4-SO2 Electrochemical Sulfur Dioxide Gas Sensor For Sulfur Dioxide Detection In Industry And Environmental Protection

Product Description:

ME4-SO2 Electrochemical Sulfur Dioxide Gas Sensor For Sulfur Dioxide Detection In Industry And Environmental Protection

Features:

ME4-SO2 type sensor is a constant potential electrolysis type SO2 sensor. SO2 and O2 undergo corresponding REDOX reaction at the working electrode and the opposite electrode and release charge to form current, the current is proportional to the concentration of SO2, and the concentration of SO2 can be determined by testing the current size.
