O2-A2 Oxygen Sensor

Oxygen Sensors (O2)

Oxygen makes up 21% of the atmosphere by volume. This is halfway between 17% (below which breathing for unacclimatised people becomes difficult) and 25% (above which many organic compounds are highly flammable). The element and its compounds make up 49.2% by mass of the Earth’s crust, and about two-thirds of the human body.

Accurate measurement of Oxygen is core to Alphasense’s portfolio, whether it’s required for safety, medicine, air quality or specialist processes.

Alphasense Oxygen Sensors (O2 sensors) have proved the test of time as cost-effective, low cost and robust in a host of applications. Unlike partial pressure oxygen sensors, our design has good pressure and temperature dependence, making it the best choice in safety applications. Our lead-free O2 sensor range has a significantly increased lifetime over a lead-based sensor – minimising the likelihood of sensor leaks and making mid-contract servicing a thing of the past.
