Model 7E4-NO2-5 Sensor -4-Electrode NO2 Gas Sensor
This 4-electrode sensor is designed for air quality monitoring to measure the low-concentration NO2 gas with ultra-high resolutions. The design optimizes the sensor sensitivity, accuracy and long-term stability and enables the sensor to detect ozone variations at parts per billion (ppb) levels.
