LH2002 DPD Residual Chlorine Reagent Kit, 0.05-1 mg/L (CAT#: STEM-AL-4053-ZJF)

LH2002 DPD Residual Chlorine Reagent Kit is a reagent kit for determination of residual chlorine in water samples. The procedure uses supplied reagents and a visual color comparison or titration step. Sample and reagent volumes are added according to the documented sequence. The developed endpoint or color is matched with the supplied reference scale. The kit provides a defined concentration range for routine field or laboratory checks. Premeasured reagents reduce preparation work during testing. The stated reaction time and sample conditions should be maintained. Compact packaging supports transport and storage between tests. The kit supports repeatable screening within the documented test range.
