A Series Oxygen Sensors

The O2-A1/A2/A3 sensors are designed for the latest generation of portable gas detectors where high detection performance, total reliability, small size and long lifetime are the key criteria.

Our high quality engineering ensures that the O2-A1 has a minimum 1-year working life and the A2, a 2-year working life, both with our electrolyte leak-free guarantee. The latest addition to this family is the O2-A3 which provides 3 years of working life.

The 'A' oxygen family is the choice for many gas detector manufacturers.

Alphasense tests the performance of every sensor; results are stored on our database, giving full traceability for all sensors. The unique Automatic Test and Validation (ATAV) system controls initial sensor stabilisation and runs complex tests under computer control. This computerised system also ensures traceability as tested sensors are moved direct to despatch with their unique barcodes. The ATAV system also runs full validation testing, monitors sensors for long term performance and its generated statistics are used for process control.
