5.2 Calibration

5.2.1 Purpose of calibration

Please remove the watering cap from the sensor,
rinse the sensor with water and dry it for at least 10
minutes before starting calibration.
A zero point calibration is only advisable if very high
accuracy is required at low oxygen concentrations.
To check if your sensor needs a recalibration, you
may dry it and take it in the air to check that the
reading is close to 100 %. If not, then the sensor
needs a new calibration.

5.2.2 What you have to know for calibration

Attention!
Standard applications
(e.g. measurement in
biotechnology).
No special procedure required.
Refer to transmitter instruction
manual and general remarks below.
First step:
Where is oxygen
being measured?
Measurement of permanently low oxygen
concentrations (<500ppb) in the pre-
sence of volatile acidic components
(e.g. CO
2
at measurements in breweries).
Follow step 1 to step 4
and general remarks
below.
