The ODO sensor should be kept clean since some types of fouling may
consume oxygen which could affect the dissolved oxygen measurements.
To clean the sensor cap, gently wipe away any fouling with a lens cleaning
tissue that has been moistened with water to prevent scratches
66). Do not clean the ODO sensor with organic solvents as they may
damage the cap.
To minimize sensor drift, always store the ODO sensor in a wet or water-
saturated air environment.
Short-term Storage:
Store the ODO sensor in a moist air environment. A storage sleeve with
a wet sponge or the calibration cup with a small amount of water is
recommended
(Figure
Long-term Storage:
• Method 1: Submerge the sensing end of the sensor in a container of
distilled or deionized water. Periodically check the level of the water to
make sure that it does not evaporate.
• Method 2: Wet the sponge located in the cap originally included
with the ODO sensor, then install on sensing end of the ODO sensor.
Replace the sponge if it becomes dirty.
For ProDSS ODO sensors, the sensor can be left on the 4-port bulkhead
or removed for long-term storage
67).
