ME3-NH3 ammonia gas sensor
ME3-NH3 electrochemical gas sensor is based on the principle of electrochemistry, using the measured gas to have 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, thus Realize quantitative measurement of target gas.
