Measuring Free Chlorine When Chloramines Are Present

The presence of chloramines can often be a concern when trying to test for free chlorine. It has been widely tested by Kuntze R&D, and other institutions, that Kuntze's  free chlorine measurements do not respond and/or detect chloramines. 

Note: Please consider the behavior, capabilities, and limitation of the reference measurement (DPD) in regards to this discussion.  For more information, please contact your DPD reagent supplier and/or manufacturer to learn more.
