The Online Analyser for Chlorine without reagent STAC CL is difficult today to measure chlorine whose concentrations fluctuate from 4 mg/L up to 3 g/L.
The problem still becomes complicated if measurement must be automated.
The solutions which exist to measure chlorine are:
- The colorimetry using reagents and titrimetry. These methods are not easy to use on line and relate to only the
small concentrations (1.5 mg/L). - Potential “Redox” measurement. Although usable in process, the measurement carried out by probe makes dilution impossible during strong concentration.
- SECOMAM offers a powerful and easy to use on line alternative by direct physical measurement in the UV of the chlorine concentration from 4 mg/L up to 3 000 mg/L . Much more SECOMAM Analyzer can simultaneously measure Dissolved Sulfide (H2S) in 5 – 50 mg/L range.
