ME4-NO2-E4 Outdoor Nitrogen dioxide Gas Sensor 50ppm Constant Potential Electrolytic Type
ME4-NO2-E4 sensor is a constant potential electrolytic NO2 sensor. The corresponding redox reaction between NO2 and O2 occurs on the working electrode and the counter electrode, and the charge is released to form a current. The magnitude of the generated current is proportional to the concentration of NO2. The concentration of NO2 can be determined by testing the magnitude of the current. The fourth electrode of the sensor, the auxiliary electrode, is used to compensate the zero-point current, so that it has the characteristics of strong signal level and low zero-point current.
Main application
It is widely used in urban atmospheric environment monitoring, enterprise environmental monitoring, unorganized emission pollution gas monitoring in factories, emergency monitoring and environmental assessment monitoring.
