Colorimetric online analyser for determining disinfectants, such as free chlorine, chlorine dioxide, ozone or bromine.
The AMI Codes-II continuously measures the concentration of disinfectants, such as free chlorine, chlorine dioxide, ozone or bromine. The analytical principle is based on the well-established DPD colorimetric method (EN ISO 7393-2 and APHA 4500-Cl G). Diagnostic functions like automatic zero-point determination or flow control enhance measurement accuracy and reliability. A pH measurement or a cleaning module can be added to increase operational efficiency.
Key Features
- Analysis of free chlorine, chlorine dioxide, ozone or bromine.
- Adjustable measurement intervals reduce operating costs while protecting health and the environment.
- User-friendly solid-state verification kit for the photometer to maintain measurement accuracy.
- Diagnostics such as automatic zero-point determination and flow control enhance measurement accuracy and reliability.
- No measurement interference from seawater, effluents, or additives such as corrosion inhibitors and antiscalants.
- Complete plug-and-play system, wet bench-tested and calibrated, ready for operation.
