Product Description
ME3-NO2 Nitrogen Dioxide Sensor Electrochemical Principles



ME3-NO2 electrochemical gas sensor is based on the principle of electrochemistry, using the measured gas to have the corresponding redox reaction on the working electrode and the counter electrode of the sensor and release the charge, and form a current through the external circuit, the current size is proportional to the gas concentration, thus Realize quantitative measurement of target gas.
