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
