UK alphasense dual-gas carbon monoxide/hydrogen sulfide sensor (CO/H2S sensor)
The dual-gas carbon monoxide/hydrogen sulfide sensor provides an excellent approach in terms of external dimensions and electrode structure. Using a high-capacity filter on the carbon monoxide working electrode can completely eliminate cross-sensitivity to hydrogen sulfide, acid gases, and similar gases such as sulfur dioxide and nitrogen oxides. In portable instrument design, the COH-A1 series sensor enables precise factory-level maintenance and field-level calibration for mixed gases, without worrying about incorrect adjustment of the CO channel.
