Industrial Nitrogen Monoxide Gas (NO) Sensor

General Description:

The NE4-NO is an electrochemical gas sensor with 3 electrodes for the detection of Nitrogen Monoxide (NO) in a variety of industrial and commercial gas detection applications.

Exhibiting high performance with long-term stability, this compact (20.4mm 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.
