6 Sensor maintenance

6.1 Cleaning

Cleaning the sensor after each use extends the service life of the sensor membrane.
1. The sensor must be rinsed off with distilled water after each use. No aggressive solutions
or alcohols may be used.
2. Carefully remove any type of dirt on the sensor membrane with a cloth, particularly if
the measurements are conducted in solutions containing chemicals. Ensure that the sensor
membrane is not damaged by scratches.

6.2 Safekeeping

The oxygen sensor must be stored in a moist environment in the supplied storage flask when
it is not being used for measurements.
The sensor can be stored in clean water or water-saturated air for short storage periods of
up to one week or between measurements.
For extended storage periods, the sensor should be stored in the storage flask, which contains
a moist sponge. In order to prevent soiling the sponge, a hygienic working environment is
recommended, as well as the use of distilled water. It should be checked regularly to ensure
that the sponge does not dry out.
If the sensor is stored dry, measurement values may deviate with the next measurement. Before
measurement the sensor must be rehydrated and recalibrated as necessary.

6.3 Replacement of the sensor membrane

The sensor membrane must be replaced if:
- The membrane is damaged (chemically, mechanically)
- No stable measurements are obtained
- The service life of the membrane has elapsed
Even if no chemical or mechanical damages have occurred, the sensor membrane should be
replaced at least every 2 years in order to obtain precise measurement results (refer to "Ac-
cessories" for the item number).
