2. Product Description
Application
Range
The AMI Codes-II analyzer is a complete monitoring system for the
automatic, continuous measurement and dosing control of chlorine
and other disinfectants based on the DPD colorimetric method
AWWA 4500 Cl-G and on EN ISO 7393-2.
It can be used for measuring disinfectants in:
Potable water
Swimming pools
Cooling water
Effluent
Seawater
It is also applicable for water containing additives like corrosion in-
hibitors, cyanuric acids and antiscalants.
For the determination of free chlorine, chlorine dioxide, bromine
and iodine the reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
are needed.
The measurement of monochloramine or ozone requires an addi-
tional reagent:
Oxycon on-line KI; which is added to Oxycon on-line Buffer

Outputs
Two signal outputs programmable for measured values (freely
scaleable, linear or bilinear) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510
Third signal output available as an option. The third signal output
can be operated as a current source or as a current sink (selectable
via switch).
