7.3 Function of the AQC-D6

The AQC-D6 measuring cell is used to determine the chlorine
dioxide concentration in potable water.
Sample water is taken at a representative position and fed to the
measuring cell.
The sample water flow rate can be adjusted on the flow fitting.
A water sensor can, for example, be used to trigger an alarm
or to switch off the control functions if there is insufficient
sample water.
The substance to be determined (ClO
noble-metal electrode.
The material to be determined (ClO
current:
The electric current is in the µA range.
The electric current is proportional to the concentration of the
ClO
parameter.

The measuring cell is controlled with a potentiostat integrated in
the measuring amplifier.
A precisely defined potential of the measuring electrode is
retained through a reference system. This results in a linear
response for the measuring cell as well as a stable zero point for
the measurement.
The measuring amplifier and regulator of the Oxiperm Pro
chlorine dioxide system:
amplifies the current
calculates it using the calibration parameters
displays the chlorine dioxide concentration as a numerical
