Product Description:

ME4-NO2-E4 Outdoor Electrochemical NO2 Gas Sensor

Features:

ME4-NO2-E4 sensor is a constant potential electrolytic NO2 sensor. NO2 and O2 undergo corresponding REDOX reaction on the working electrode and the opposite electrode and release charge to form current. The current generated is proportional to the concentration of NO2, and the concentration of NO2 can be determined by testing the current size. The sensor's fourth electrode auxiliary electrode is used to compensate the zero current, so that it has a strong signal level, low zero current characteristics.
