With over 25 years’ experience in the design and manufacture of gas and particulate sensors, we have established a reputation as a reliable source for a wide range of gas sensor technologies.

At Alphasense, we supply high-quality Oxygen, CO2, toxic and flammable gas sensors to many of the world’s leading industrial OEMs.

If you manufacture portable or fixed industrial gas detection monitors, stack gas analysers or environmental monitoring instruments, we have the solution for your needs.

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
