5. General information
This manual contains all important information for users of the
AQC-D13 and the preassembled systems:
•
technical data
•
instructions for start-up, use and maintenance
•
safety information.

6. Applications
The potentiostatic measuring cell AQC-D13 measures the
concentration of chlorine (Cl
) in the pH-range 4.5 to 8.2, chlorine
2
dioxide (ClO
) or ozone (O
). By means of the suitable
2
3
electrodes, it can also measure the pH value and redox potential
for treatment of swimming-pool water and drinking water.
The preassembled systems measure and control the following
parameters, depending on the measuring amplifier and controller
installed:
•
Preassembled system with Conex DIA-1 measuring amplifier
and controller:
– Measurement: free chlorine (Cl
compensation, chlorine dioxide (ClO
temperature.
– Control: chlorine (Cl
), chlorine dioxide (ClO
2
•
Preassembled system with Conex DIA-2 measuring amplifier
and controller:
– Measurement: free chlorine (Cl
compensation, chlorine dioxide (ClO
temperature.
– Control: chlorine (Cl
), chlorine dioxide (ClO
2
pH.
•
Preassembled system with Conex DIA-2Q measuring amplifier
and controller:
– Measurement: free chlorine (Cl
compensation, chlorine dioxide (ClO
temperature.
– Control: chlorine (Cl
), chlorine dioxide (ClO
2
pH, redox potential.
•
Preassembled system with Conex DIS-D measuring amplifier
and controller:
– Measurement: chlorine (Cl
(O
).

– Control: chlorine (Cl
), chlorine dioxide (ClO

•
Preassembled system with DIP measuring amplifier and
controller:
– Measurement: chlorine (Cl
