Alphasense sensors use technologies that best suit the individual application.
While electrochemical amperometric sensors are popular because of their low power and selectivity, some applications operate in environments that extend beyond their capability. To meet those demands, Alphasense has introduced a new class of metal oxide gas sensor.

Traditional n-type metal oxides suffer from baseline drift and humidity sensitivity however Alphasense p-type metal oxide gas sensors have more stable baselines and very low humidity sensitivity.

Three variants have been designed for specific markets:

H2S detection at high temperatures (up to 120oC) for oil and gas applications
Volatile Organic Compounds (VOCs) for low cost IAQ applications
CO detection for environments at extreme temperatures and/ or humidities
