Storage

For storage periods longer than 24 hours, we re-
commend you to use a protection cap filled with the
same cleaning and conditioning solution as that
used for our portable DO measurement system (order
no. 52 200 255). This solution contains an oxygen
scavenger which ensures that the electrolyte of the
s ensor does not come into contact with oxygen when
not in use.
When the sensor is stored without polarization
for more than one week, the electrolyte has to be
removed.
Prepare the cleaning and conditioning solution as
f ollows: Dissolve one tablet in 40 ml of deionized
w ater and wait 5 minutes for the tablet to be com-
pletely d issolved. Fill the protection cap with this
solution and place it over the tip of the sensor. This
solution has some cleaning properties which will
keep the m embrane free of microorganisms. In case
you do not have any cleaning and conditioning set,
you may a lso use checking gel or deaerated water in
the protection cap. Before mounting the sensor in the
process, always remove the protection cap and rinse
the tip of the s ensor with water.
a
Attention! If the storage period of the sensor with-
out current supply (transmitter, sensor master)
exceeds 1 week, the sensor should be stored dry,
i.e. without any electrolyte in the membrane body.
A sensor being stored dry (without electrolyte
in the membrane body) may on no account be
connected to the O
polarization module.
