O2-C2 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.

O2-C2 Oxygen Sensor size:
20mm diameter, extra height allows additional filter material when measuring combustion gases
