METTLER system: 1-point calibration in the calibration menu
of the redox parameter in the touch screen software from the
administrator user level.
HAMILTON system: Calibration using a Hamilton Arc
Handheld or a Hamilton Arc USB cable, both of which are
available separately from the sensor manufacturer.
In case of a deviation of ± 10 mV from the buffer solutions, clean
the redox sensor according to the description provided by the re-
spective sensor manufacturer or contact the sensor manufacturer.
For details on the technical data, usage and maintenance require-
ments for the redox sensors, see the separate documentation pro-
vided by the respective sensor manufacturer, i.e. METTLER TO-
LEDO or HAMILTON.
4.8.3 Mounting the Sensor
Redox sensors (both variants) are mounted into a 12 mm / Pg13.5
port in the vessel top plate by the means of an electrode holder. An
additional adapter is necessary for mounting the sensor into a
19 mm port. For details about the electrode holder see chapter
“Accessories”, “Electrode Holder”.
4.9 pCO
2
Measurement
Measures saturation of dissolved carbon dioxide (CO
2
) in the cul-
ture in hPa. Measurement is done by a digital CO2 sensor with in-
tegrated temperature sensor. Measured values are displayed on
the associated transmitter and in the touch screen software.
Type of sensor (digital): InPro5000i ISM
Measuring principle: potentiometric
Type of transmitter: M400
Manufacturer (sensor & transmitter): METTLER TOLEDO
The displayed value of parameter pCO2 in the touch screen soft-
ware is set to a range of 0 hPA to 1000 hPA analogous to the dis-
played value of the transmitter.
If a CO2 gassing line is present and configured with a mass flow
controller (parameter
CO2 Flow
), then this can be used e.g. via
cascades for pCO
2
control.
Calibration of the sensor is carried out directly on the transmitter
according the sensor manufacturer’s specifications.
