Electrochemical carbon monoxide (CO) sensor with low hydrogen cross sensitivity
A series Alphasense

Alphasense Carbon Monoxide sensors operate using proven fuel cell technology. All sensors have an active chemical filter to remove NOx and SO2/H2S.

The CO-AX provides low hydrogen cross sensitivity in a three-electrode format, which can also be retro-fitted into standard carbon monoxide measuring instruments.

Choose the right CO sensor in the standard 20mm diameter:

CO-AF: robust, general purpose sensor
CO-AE: extended range sensor, operates to 10% CO
CO-AX: TUV-approved, low hydrogen sensitivity sensor

The A series CO sensors show excellent long-term stability and resistance to environmental extremes, proven by years of validation history.
The CO-A sensors offer our electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is moulded with a colour coded top for ease of identification.
Alphasense tests the performance of every sensor; results are stored on our database, giving full traceability for all sensors. The unique Automatic Test and Validation (ATAV) system controls initial sensor stabilisation and runs complex tests under computer control. This computerised system also ensures traceability as tested sensors are moved direct to despatch with their unique barcodes. The ATAV system also runs full validation testing, monitors sensors for long term performance and its generated statistics are used for statistical process control.
