Online Analyzer for Chlorine without reagent STAC CL
CONTEXT
It 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.
We 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..
MEASURED PARAMETER
In this operation, H2S is dissolved at basic Ph, and then converted into Sulfate by Chlorine. The STAC Cl is able to trace both Chlorine & Sulfide.
MEASURING RANGE
It is possible to work on three ranges of measurement according to the size of the flow though cell used (2mm, 5mm)
| Optical path of cell | Chlorine measuring range | Sulfide threshold detection |
| 2mm | From 100 to 3000 ppm | 10 ppm |
| 5mm | From 40 to 1200 ppm | 4 ppm |
