7E4-NH3-10 4 059-3500-200 NH3 Gas Sensor Electrode Ultra High Resolutions Air Quality Monitoring
This 4-electrode sensor is designed for air quality monitoring to mea- sure the low-concentration NH3 gas with ultra-high resolutions. The de- sign optimizes the sensor sensitivity, accuracy and long-term stability and enables the sensorto detect NH3 variations at parts per billion (ppb) levels.
