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
sensor 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 re-
moved.
Prepare the cleaning and conditioning solution as
follows: Dissolve one tablet in 40 ml of deionized
water and wait 5 minutes for the tablet to be com-
pletely dissolved. Fill the protection cap with this so-
lution and place it over the tip of the sensor. This so-
lution has some cleaning properties which will keep
the membrane free of microorganisms. In case you
do not have any cleaning and conditioning set, you
may also 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 sensor with water.
Attention! If the storage period of the sensor with-
out current supply (transmitter, sensor master) ex-
ceeds 1 week, the sensor should be stored dry, i.e.
without any electrolyte in the membrane body. A sen-
sor being stored dry (without electrolyte in the
membrane body) may on no account be connected
to the O
module.
