Colorimetric online analyser for determining total chlorine concentration
The AMI Codes-II TC continuously measures the concentration total chlorine and dichloramine is accessed through calculation. 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
- Determination of total chlorine and dichloramine.
- 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 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.
