DANGER
Use caution when handling oxygen at levels above 40 vol. % O
2
- high oxygen levels
can cause ignition of materials and explosion if not handled properly
_
NOTE
This device does not belong in children's hands!
_
DANGER
The sensor contains potassium hydroxide (GOEL 381 at G 1690..-MAX) or acid
(GOEL 370 at G 1690..-35).

Intended use
_
The device is to be used exclusively for measuring the oxygen concentration in gas
mixtures and air. The measurement is made at the sensor opening.
The device must be calibrated regularly (in fresh air =20.95% vol.-% O
2
) to obtain
accurate readings.
The G 1690T is also suitable for displaying the calculated maximum operating depth
(MOD) from the measured oxygen concentration.
