ME3-NH3 Gas Sensor Ammonia Electrochemical Principles

Place of Origin: China
Brand Name: Winsen
Model Number: ME3-NH3
ME3-NH3 electrochemical gas sensor is based on the principle of electrochemistry, using the measured gas to undergo corresponding redox reactions on the working electrode and counter electrode of the sensor and release charges, and form a current through an external circuit. The current size is proportional to the gas concentration, thereby Realize quantitative measurement of target gas.
