O2-A2 Oxygen Sensor (O2 Sensor), 20mm diameter, the industry standard size for portable gas detectors.

O2-A2 Oxygen Sensor (O2 Sensor) Description
Alphasense Oxygen sensors use capillary flow control.

Unlike partial pressure oxygen sensors, they have good pressure and temperature dependence, making them the best choice in safety applications.

Standard galavanic sensors use lead for greatest reliability but fixed lifetime.

Sensors are available in three sizes:
‍A: 20mm diameter, the industry standard size for portable gas detectors
C: 20mm diameter, extra height allows additional filter material when measuring combustion gas
G: Miniature, proven long-term performance. The sensors are designed for the next generation of portable gas detectors. Part of the Alphasense 'D' family.
