7NO2-5AOF Nitrogen Dioxide Gas Sensor Electrochemical 7Series
7NO2-5AOF refers to a 7-Series electrochemical Nitrogen Dioxide (NO2) gas sensor manufactured by companies like SemeaTech. It is designed for detecting NO2 in the environment, with a typical nominal range of 0 to 5 parts per million (ppm). This sensor features a filter to reduce cross-sensitivity to other gases like sulfur dioxide (SO2) and ozone (O3), making it suitable for air quality monitoring and industrial emission detection applications.
