Reliable colorimetric measurement using the DPD method
The AMI Codes-II CC determines chlorine concentrations using the DPD photometric method, widely recognized in international standards such as EN ISO 7393-2 and APHA 4500-Cl G.
In this process:
- A reagent is automatically added to the water sample.
- The chlorine reacts with the reagent to form a colored compound.
- A photometer measures the intensity of the color to determine the chlorine concentration.
The analyzer automatically performs the required measurement steps, ensuring stable and repeatable measurements with minimal operator involvement.
Key features supporting reliable disinfectant monitoring
- Continuous online measurement of free chlorine, total chlorine, and combined chlorine
- Detection of monochloramine and other disinfectant forms
- Accurate colorimetric measurement using the DPD method
- Integrated photometer and automatic reagent dosing
- Programmable measurement intervals to optimize reagent consumption
- Automatic zero calibration for long-term measurement stability
- Sample flow monitoring and reagent level monitoring
- Optional pH measurement with temperature compensation
These capabilities allow operators to maintain stable disinfection levels while minimizing chemical consumption.
Typical applications for chlorine monitoring
The AMI Codes-II CC is widely used in systems where controlled disinfection is essential for water safety and regulatory compliance.
Typical applications include:
- Drinking water treatment plants
