Storage

For storage periods longer than 24 hours, we re -
commend you to use a watering 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.
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 completely
dissolved. Fill the watering cap with this solution and
place it over the tip of the sensor. This solution 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 watering
cap. Before mounting the sensor in the process, always
remove the watering cap and rinse the tip of the sensor
with water.
Attention! The electrolyte should be replaced before
use if the storage period exceeds 3 months.
Attention! If the storage period exceeds 6 months,
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
Master InPro 6900.

Certificates

Each sensor is delivered with a set of 3.1 B certificates
(complying with EN 10204.3/1.B).
All wetted metal parts (sensor shaft, cap sleeve and
membrane body) are identified with a engraved
symbol corresponding to the heat number on the paper
certificate 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 (according to ISO
1320:1992).
