Maintenance
5.4 Storage
Remove the sensor from the sample flow and clean the sensor
thoroughly.
Short term storage
Keep the membranes and the salt bridge moist by using drinking
water or shipping boot solution (NO DISTILLED WATER OR
DI WATER). This will help avoid long response times when placing
the sensor back in the sample flow. Otherwise, the correct
operation of the sensor is no longer guaranteed.
Long term storage
Important Note: Use the delivered storage container for long term
storage. Fill the container with drinking water or use the shipping
boot solution (NO DISTILLED WATER) and ensure that the sensor
cartridge remains wet.
Check the membranes and ensure they are still moist every
2–4 weeks, depending on environmental conditions.
Note: A storage container is supplied to keep the sensor cartridge moist.
Keep sensor cartridge capped within the storage container during short
and long term storage. Refer to
Section 1 Specifications on page 5 for
storage temperatures.
Note: The black gasket is needed for sealing function. See Figure 6 on
page 13 .
Sensor and sensor cartridge
Note: Take care of contacts between sensor and sensor cartridge. The
contacts must be dry. Store in a dry place.
