Nitrogen Dioxide NO2 2E N gas sensor

Measuring Range: 0-20ppm NO2

Size: 4 SERIES, 2-electrode, 2-pin

Part no: 2112B9998N


A lifetime of two years, this 2-pin sensor provides an easy solution for the measurement of Nitrogen Dioxide. This sensor is often used in conjunction with the 2-electrode CO sensor range, like ECO-Sure. The NO2 2E N has standard negative output.

Directives to limit and decrease Nitrogen Dioxide emissions are becoming more commonplace around the world. Power stations and traffic are the main sources. Major road networks and urban areas have the highest levels of Nitrogen Dioxide. However, in homes with gas stoves, kerosene heaters, or unvented gas space heaters, indoor levels often exceed outdoor levels and put at risk people’s health. This sensor is particularly popular for monitoring levels in underground car parks.

Note: The graphic of this sensor is an example only and sensor cap/body colour may vary depending upon gas sensor type ordered or manufacturing modification. Please refer to individual datasheet for detailed information on this sensor and its dimensions.
