2
(6809720)
Sensor Principle
The DrägerSensor O
2
(6809720) is an electrochemical two-
electrode sensor for measuring Oxygen (O
2
) in ambient air.
CAUTION
Specifications and restrictions in the Instructions for
Use and/or data sheets for the sensors used must be
observed. For SIL applications the Dräger Polytron
8X00 Safety Manual must be observed.
The measuring range and performance
characteristics are dependent on the installed sensor
(see the Instructions for Use and/or data sheet for the
installed sensors).
