NE4-CO-SI

Carbon Monoxide (CO) Sensor for Commercial Applications

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.
