YJJ NE4-NO2 NE-NO2 Electrochemical Gas Sensors Are Used In Underground Garage Alarm Systems
Features:
NE4-N02 is an electrochemical nitrogen dioxide gas sensor developed for use in underground parking garages. Since the detected gas is an oxidizing gas, the output signal is different from that of reducing gases. It is a reverse signal, but the linearity of the signal is very good. Additionally, among the nitrogen oxide series, only nitrogen dioxide and dinitrogen tetroxide have the ability to be detected. Not all nitrogen oxides can be detected. Please note this.
