Range
The AMI Codes-II TC is a complete monitoring system for the auto-
matic, continuous measurement and dosing control of chlorine
based on the DPD colorimetric method APHA 4500 Cl-G and on
EN ISO 7393-2.
It can be used for measuring disinfectants in:
Pools and sanitary water
Cooling water
Waste water effluent
It is also applicable for water containing additives like corrosion in-
hibitors, cyanuric acid and antiscaleants.
Determines total chlorine (tc1 and tc2) and calculates dichloramine.
Necessary reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
Oxycon on-line KI

Measurement
Operating
Modes
Two operating modes are available depending on the desired mea-
suring range. Default mode “Standard” for concentrations up to 5
ppm. Select “Extended” for measurements up to 10 ppm which will
lead to higher reagent consumption.
Signal
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).
