Alphasense, the UK-based manufacturer of sensors for air quality monitoring and safety gas detection, has implemented design changes to its O2-A2 and O2-A3 oxygen sensors which sees both models now being guaranteed 100% leak free.


The new leak-free design delivers a step-change in high-temperature and humidity resistance, providing customers with a sensor solution which will not leak, even under the most arduous of applications.
The superior performance of the new sensor designs has been proven through an extensive program of accelerated life testing, during which the new sensor designs outlasted similar sensors from other manufacturers by up to 10 x when tested to destruction.
With this new iteration of its most popular O2 sensors, Alphasense cements its place as a supplier of the most robust sensors on the market.
The benefits of these new zero-failure sensors extend beyond reduced sensor replacement costs but play a critical role in reducing instrument failure rates, a common side-effect of sensor leakage. Negating instrument failures due to leakage reduces instrument downtime, improves site efficiency and removes the need for scheduled replacement in order to tail off potential leakage. With extended life comes reduced environmental impact, lower maintenance costs and instruments which are more likely to be favoured by end users.
Uniquely, the patent pending Alphasense O2-A2 and O2-A3 are fully sealed to prevent leakage, unlike many ‘low-cost’ sensors which incorporate vents in order to manage rather than prevent spills.
The new models present customers with a superior offering under the same part number, preventing the need for certification, administrative or firmware changes.
