Carbon Monoxide Sensors (CO)

Carbon Monoxide Gas Sensors

Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems. Despite advances in detection, CO, or ‘the silent killer’ as it is often referred to, is still responsible for tens of thousands of deaths each year. 

CO Sensors are available in a wide range of formats, making them suitable for use in fixed and portable detection instruments.

Alphasense CO sensors

Alphasense CO Sensors are available in a wide range of formats and both PPM and PPM variants, making them suitable for use in variety of applications, from fixed and portable detection instruments to environmental monitoring systems and networks.

A: 20mm diameter, the industry standard size for portable gas detectors
B: 32mm diameter package, the best choice for fixed site applications
C: 20mm diameter with extra height for additional filter material when measuring combustion gases
D: Miniature, with proven long-term performance. Sensors for the next generation of 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. The ‘X’ sensors have low hydrogen sensitivity, as drop-in replacements for the standard ‘F’ sensors.
