Recalibration
The recalibration is recommended for typical applications
every 6 months. However, a regular weekly check of the
oxygen reading in humid air (should be ~ 100% a.s.) can be
used to check if the sensor needs calibration.
In some applications, e.g. under harsh environmental
conditions, the sensor must be recalibrated more frequently
to guarantee precise measurements. Please check regularly
the oxygen reading of the sensor when it is placed in humid
air.
Since the florescent membrane is prone to photobleaching
effects during the measurement and is therefore an
expendable part, it can be changed by replacing the sensor
cap (Art.-No.: 2101, Type: O2S-ATK). Please note, that the
sensor must be always recalibrated, if the sensing cap is
exchanged. A typical lifetime of the sensor cap is > 2 years.
