Understanding Chlorine Measurement

Free vs. Total Chlorine Lutron CL-2006 Free & Total Chlorine Meter

The CL-2006 measures both critical forms of chlorine in water:

• Free Chlorine - The active disinfectant form (hypochlorous acid and hypochlorite ion) available to sanitize water
• Total Chlorine - The sum of free chlorine plus combined chlorine (chloramines formed when chlorine reacts with nitrogen compounds)

The difference between total and free chlorine indicates the amount of combined chlorine, which has lower disinfection power but can cause irritation and odor problems. Lutron CL-2006 Free & Total Chlorine Meter

DPD Method

The CL-2006 uses the DPD (N,N-diethyl-p-phenylenediamine) colorimetric method, which is approved by the U.S. Environmental Protection Agency (EPA) for water testing:

• Free Chlorine Test - Free chlorine reacts with DPD reagent to produce a pink color proportional to concentration
• Total Chlorine Test - Uses additional reagents to measure both free and combined chlorine forms
• Accurate Quantification - The meter's 525 nm LED light source precisely measures color intensity to determine concentration
