ME4-NO2 Electrochemical Nitrogen Dioxide Sensor Is Used For Nitrogen Dioxide Detection In Industrial Mines And Environmental Protection

Features:

ME4-NO2 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.
