Short-Term Storage – All Sensors
The cable assembly is supplied with a sensor storage container, or sleeve, that attaches to the cable. The container is used for short-
term storage (less than 30 days). Be sure to keep a small amount of moisture (tap water) in the container during storage. This is done
to maintain a 100% saturated air environment which is ideal for short-term sensor storage. The sensors should not be submersed in
water. The intent is to create a humid air storage environment.
Temperature Sensor Long-term Storage
No special storage is required. The temperature sensor can be stored dry or wet as long as solutions in contact with the thermistor
are not corrosive (for example, chlorine bleach). The storage temperature should be -5 to 70 °C (23 to 158 °F).
Conductivity Sensor Long-term Storage
No special storage is required. Sensors can be stored dry or wet as long as solutions in contact with conductivity electrodes are not
corrosive (for example, chlorine bleach). However, it is recommended that the sensor be cleaned with the provided brush prior to
and after long term storage. The storage temperature should be -5 to 70 °C (23 to 158 °F).
Dissolved Oxygen Sensor Long-term Storage
Dissolved oxygen sensors (Polarographic and Galvanic) should be stored in a dry state for long term storage First, remove the
membrane cap and thoroughly rinse the sensor with clean water. Next, either blow it dry with compressed air or allow to air dry
completely. Install a clean, dry new membrane cap over the sensor to keep it dry and to protect the electrodes. with compressed air
or allow to air dry completely. Install a clean, dry new membrane cap over the sensor to keep it dry and to protect the electrodes.
After storing the sensor for a long period of time, it is necessary to “condition” the sensor by putting a new membrane with
electrolyte solution on the sensor and then turning the instrument on to allow the sensor sufficient time to stabilize.
The storage temperature should be -5 to 70 °C (23 to 158 °F).
