14.3.1 DrägerSensor O
2
(6809720)
The DrägerSensor O
2
(6809720) is an electrochemical two-electrode sensor for the
measurement of oxygen (O
2
) in the ambient air. The sensor measures the
O
2
-partial pressure. Changes in pressure have an effect on the measured value in
this process. For 1013 hPA without oxygen depletion the sensor measures
20.9 vol% O
2
.
