O2-A3 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-A3 Oxygen Sensorsize:
20mm diameter, the industry standard size for portable gas detectors
