Maintenance
5.4 Storage
Take the probe out of the sample flow and clean thoroughly.
Short term storage
Keep the membranes and reference system moist (do not use distilled or demineralized
water).
This will help avoid long response times when the probe is placed back in the sample flow.
Otherwise, the correct operation of the probe is no longer guaranteed.
N O T I C E
Long term storage
Check the membranes and ensure they are still moist every 2–4 weeks, depending on
environmental conditions.
N O T I C E
Note: A storage container is supplied to keep the sensor cartridge moist. Keep the sensor cartridge
sealed in the storage container during short and long term storage. Refer to
Section 1 Technical
data, Page 5 for information on storage temperatures.
Probe and sensor cartridge
Detach the cartridge and use the supplied storage container in the event of long-term storage.
Moisten the little sponge in the storage container with drinking water (DO NOT USE DISTILLED
WATER!) and make sure that the ISE membranes of the sensor cartridge remain wet. Attach the
reference system cap.
Pay attention to the contacts between the probe and the sensor cartridge. These contacts must be
dry.
