Carbon Monoxide (CO) Sensor for Industrial Applications

General Description:


The NE7-CO is an electrochemical gas sensor with 3 electrodes for the detection of Carbon Monoxide (CO) in the range 0-1000ppm. The sensor is the first standard

“7-series”, 32mm diameter sensor manufactured by Nemoto.


Designed for general purpose use within fixed toxic gas Detection heads in industrial safety applications, the sensor may also be used for a wide range of other applications where reliable and accurate detection of CO levels in air is required.
