This can be done on the operating panel, either before or after
autoclaving, depending on the application in question. For more
details, see the main chapter “Operation” chapter “Calibrating the
Turbidity Sensor”.
4.1.3 Mounting the Sensor
For culture vessels with nominal widths of 90 and 145, Optek ASD
sensors can be mounted directly into 12 mm/Pg13.5 ports. For cul-
ture vessels with a nominal width of 115, an electrode holder is
used. For more details on the electrode holder, see the “Accesso-
ries” section, sub-section “Electrode Holder”.
Please note the following points when mounting the components:

Ensure that the sensor is fitted with an O-ring; fit an O-ring if
necessary.

Mount the sensor by hand – do not use any tools!

If the mounting depth of the sensor is adjustable (mounting
with electrode holder), make sure the mounting depth is set
correctly prior to autoclaving, as later adjustment represents a
contamination risk.

Mount the sensor in such a way that it cannot come in contact
with other components or the glass vessel.

Mount the sensor in such a way that it has good access to the
flow and there is no risk of bubbles collecting in the measure-
ment gap.
4.1.4 Cleaning and Storing the Sensor
A build-up of deposits on the sapphire window will cause shifts in
the zero point and restrict the dynamic range of the sensor. As
such, the sapphire window on the sensor must be checked for de-
posits before each use and cleaned if necessary.
If necessary, store the Optek sensor in a clean, dry place at a tem-
perature of between -20°C and 70°C.
