O2-M2 Oxygen 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.
