All information about the ABER Futura system is available in the
separate documentation provided by the manufacturer.
4.8 Redox Measurement
Measures the reduction/oxidation potential (redox) in the medium.
4.8.1 Measuring Systems (Sensors)
Two systems are available for redox measurement:
METTLER version (analogue)
Classic combined sensor (oxidation reduction potential meas-
urement against a reference)
Type: 405-DPAS-SC-K8S
Manufacturer: METTLER TOLEDO
Measures the reduced potential in the medium in the range
from
-2,000 mV to +2,000 mV.
To use the sensor, the basic unit must be equipped with a corre-
sponding connection.
HAMILTON version (digital)
Classic combined sensor (oxidation reduction potential meas-
urement against a reference) with integrated electronics
Type: Easyferm Plus ORP ARC
Manufacturer: HAMILTON
Measures the reduced potential in the medium in the range
from
-1,500 mV to +1,500 mV.
If the basic unit is configured for Hamilton sensors, the redox sen-
sor can be connected instead of the pO
2
sensor. If the sensor is
configured in addition to the Hamilton pO
2
sensor or if the basic
unit is configured for Mettler sensors, an additional connecting ca-
ble is required.
4.8.2 Calibration
The redox sensor is usually not calibrated/adjusted. However, the
calibration of the sensor can be checked using the appropriate re-
dox buffer solution.
