UK Alphasense dual gas sensor, sulfur dioxide and hydrogen sulfide sensor (SO2+H2S)
The SOH-A2 sensor offers a unique approach in terms of external dimensions and electrode structure, using a high-capacity filter on the sulfur dioxide working electrode to completely eliminate cross-sensitivity of the channel to hydrogen sulfide, acid gases, and nitrogen oxides. In portable instrument designs, the SOH-A2 series sensor enables precise factory-level maintenance and field-level calibration of mixed gases, without worrying about incorrect adjustment of the SO2 channel.
