NE7-NO2
Electrochemical Nitrogen Dioxide (NO2) Gas Sensor

General Description:

The NE7-NO2 is a new electrochemical gas sensor with 3 electrodes for the detection of Nitrogen Dioxide (NO2) in a variety of industrial and commercial gas detection and Environmental monitoring applications.

Exhibiting high performance with long-term stability, this compact (32mm dia) sensor is suitable for portable Gas Detection Instruments or Fixed Gas Detection heads.

 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.
