5.2.2 Environmental pressure, water depth and air pressure
The environmental pressure, water depth and air pressure play an important role at the place
of measurement for the following points:
Calculation of oxygen saturation in %. Clean water can achieve 100 % saturation in air.
There must be no oxygen-depleting processes, such as biological decaying processes,
chemical effects or oxygen enhancing processes, such as excessive ventilation or
photosynthesis. This could result in an oversaturation above 100%.
Calculation of the oxygen concentration in mg/l
The valuation of calibration.
Adjusting the pressure parameter on the device is recommended prior to calibration. In the
scope of measuring accuracy, specifying the current air pressure in the region based on
meteorological data or the standard pressure based on sea level is sufficient.
For example:
0 m above NN:
1013 hPa
300 m above NN:
978 hPa
600 m above NN:
943 hPa
1000 m above NN: 899 hPa
5.3 Commissioning, filling and maintenance of the sensor
The sensor is delivered filled. Therefore, the sensor is ready for immediate operation. The
initial filling is thereby unnecessary and you can begin with calibration of the sensor
immediately – for this please refer to chapter 6.2.
If the sensor can no more be calibrated or only unstable values are displayed, it has to be
maintained or even or the membrane head has to be exchanged.
Note
After filling a time of ~ 2 hours has to be considered, until the sensor has stabilized.
Note
Wear suitable gloves*) and protect your eyes with safety goggles when filling the
electrolyte!
Do not touch the electrolyte with bare skin, if there was contact rinse sufficiently with
water.
