CO-AE Carbon Monoxide Sensor Description
Alphasense Carbon Monoxide gas sensors operate using proven fuel cell technology.

CO-AE Carbon Monoxide Sensor sizes:
20mm diameter, the industry standard size for portable gas detectors

The Alphasense family of CO sensors have proven themselves in the field with long term stability and reliable operation, well beyond the two-year warranty, using our patented electrode technology.
