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 electro-
lyte 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
removed.
Prepare the cleaning and conditioning solution
as f ollows: Dissolve one tablet in 40 ml of deion-
ized w ater and wait 5 minutes for the tablet to be
completely dissolved. 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 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.
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.

Product specification

8.1 Certificates

Each sensor is delivered with a set of 3.1 certifi-
cates (complying with EN 10204).
All wetted metal parts (sensor shaft, cap sleeve and
membrane body) are identified with a engraved
s ymbol corresponding to the heat number on the
p aper c ertificate delivered with the sensor.
Each wetted metal part (sensor shaft, cap sleeve
and membrane body) is polished in order to get a
surface roughness lower than 0.4 µm (16 µin). This
represents a roughness grade number of N5 (ac-
cording to ISO 1320:1992).
