Common O2-a2 Electrochemical Oxygen Sensor O2 Sensor

We are an authorized Trader of O2-A2 Electrochemical Oxygen Sensor O2 Sensors in Guangdong, China. 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:
20mm diameter, the industry standard size for portable gas detectors
