Product Specification

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

CO-CE Carbon Monoxide Sensor size:
20mm diameter with extra height for additional filter material when measuring combustion gases

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.
