ME2-C2H5OH Alcohol Sensor

ME2-C2H5OH-Ф16 sensor is a galvanic electrochemical sensor. The corresponding redox reaction of C2H5OH and O2 occurs on the working electrode and the counter electrode, and the charge is released to form a current. The generated current is proportional to the concentration of C2H5OH and follows Faraday's law. The concentration of C2H5OH can be determined by testing the magnitude of the current.
