Chemscan® UV-2150-S Chloramination

On-line, timely and accurate Chloramination Process Analyser for Chloramination monitoring and control in water and wastewater treatment plant applications.


The ChemScan® Process Analyzer / Chloramination Suite Analyser, uses multiple wavelength light absorbance data to characterize the concentration of free chlorine in a sample of known or stable pH. If the pH is not known or is variable, sample pH can be adjusted to the 4-5 range, where HOCl is 100% of the form or to the 10+ range where OCl- is 100% of the form.

Multiple wavelength absorbance can also be used to measure organics, nutrients or metals that may be present in the influent to chlorination process in order to calculate the effect that these constituents may have on the chlorination process.
