MNS-4NO2-20 Electrochemical Nitrogen Dioxide NO2 Gas Sensor
Product Description
MNS-4NO2-20 Electrochemical Nitrogen Dioxide Gas Sensor
The MANORSHI MNS-4NO2-20 is an electrochemical gas sensor designed for nitrogen dioxide (NO2) detection.
The target gas undergoes oxidation-reduction reactions at the working electrode and counter electrode, releasing electric charges and generating a current through the external circuit. The generated current is proportional to the gas concentration, enabling quantitative measurement of nitrogen dioxide. MNS-4NO2-20 Nitrogen Dioxide ga…
