General Description:
The NE4-CO-SI is a low cost electrochemical gas sensor with 3 electrodes for the detection of Carbon Monoxide (CO) 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 NE4-CO-SI has been developed as a lower cost alternative to the
NE4-CO sensor for use in more cost sensitive applications such as underground
Car-Park monitoring systems.
