Honeywell E3NO2 Nitrogen Dioxide Sensor Cartridge is a replaceable sensing module designed for nitrogen dioxide detection in compatible Honeywell gas-detection systems. As the NO2 sensing element, it enables ongoing monitoring of nitrogen dioxide levels in environments that require hazardous gas detection, such as industrial facilities and laboratories. The cartridge is designed for use with Honeywell detectors that accept E3-series sensor cartridges, providing a straightforward maintenance path for NO2 measurement.
