5. General information
This manual contains all important information for users of the
AQC-D12 and the preassembled systems:
• technical data
• instructions for start-up, use and maintenance
• safety information.
Should you require further information, or should problems occur
which are not handled in sufficient depth in this manual, please
contact Grundfos.
6. Applications
The potentiostatic measuring cell AQC-D12 measures the
concentration of chlorine (Cl
2
) in the pH-range 4.5 to 8.2, chlorine
dioxide (ClO
2
) or ozone (O
3
). By means of the suitable
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
2
), as an option with pH
compensation, chlorine dioxide (ClO
2
), ozone (O
3
), pH,
temperature.
– Control: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone (O
3
).
• Preassembled system with Conex DIA-2 measuring amplifier
and controller:
– Measurement: free chlorine (Cl
2
), as an option with pH
compensation, chlorine dioxide (ClO
2
), ozone (O
3
), pH,
temperature.
– Control: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone (O
3
),
pH.
• Preassembled system with Conex DIA-2Q measuring amplifier
and controller:
– Measurement: free chlorine (Cl
2
), as an option with pH
compensation, chlorine dioxide (ClO
2
), ozone (O
3
), pH,
temperature.
– Control: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone (O
3
),
pH, redox potential.
• Preassembled system with Conex DIS-D measuring amplifier
and controller:
– Measurement: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone
(O
3
).
– Control: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone (O
3
).
• Preassembled system with DIP measuring amplifier and
controller:
– Measurement: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone
(O
3
), pH, redox potential, temperature.
– Control: chlorine (Cl
2
), chlorine dioxide (ClO
2
), ozone (O
3
),
pH.
