General Description:

The NAP-550 is a new electrochemical gas sensor with 3 electrodes for the detection of Nitrogen Dioxide (NO2) in a variety commercial gas detection applications. Exhibiting high performance with long term stability, this compact sensor is suitable for portable or disposable Gas Detection Instruments or Fixed Gas Detection heads alike. The NAP-550 is a version of the popular NE4-NO2, designed to be mechanically compatible with the NAP-505 CO sensor. The two sensors working together represent unbeatable value, especially in the field of underground car park monitoring.

Nemoto's porous electrode technology enables accurate gas detection with high sensitivity. The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage.
