Accurate, Reliable Results

The Hach CL17 Chlorine Analyser uses colorimetric DPD chemistry to monitor water continuously for free or total residual chlorine or permanganate. The CL17 is a simple, dependable and economical alternative to instruments that rely on electrodes or complex procedures. The CL17 analysis method is not affected by changes in chlorine concentration, sample pH, temperature, flow or pressure, thus offering more accuracy than other methods in today's market.

Simple, Predictable Maintenance

Both an alarm for manual chlorine feed control and a 4 - 20 mA output for automatic control of chlorine feed pumps is available in the CL17 Analyser. When set for manual control, the instrument notifies the operator of out-of-limit chlorine levels for manual intervention in the disinfection process as needed. For automatic control of chlorine feed pumps, the CL17 can use one of two methods: 1. On-Off Control turns the feed pumps on when chlorine levels fall too low for disinfection and off when levels rise above a pre-set limit. 2. Proportional Control adjusts the amount of chlorine in proportion to the strength of the CL17's output signal.

Factory Calibrated

Routine maintenance can typically be performed in 15 minutes per month because the sample cell and reaction chamber are easy to clean and the case provides quick access. (Difficult samples may require more frequent cleaning.) The CL17 is also equipped with self-testing diagnostics.

EPA Compliant

Free Residual Chlorine - The CL17 Chlorine Analyser uses an aqueous buffered colorimetric indicator - N,N-diethylphenylenediamine (DPD) - to determine levels of chlorine. DPD turns a magenta color in response to the amount of free residual chlorine (as hypochlorous acid or hypochlorite ion). The reaction takes place at a buffered pH of 6.3 - 6.6. Total Residual Chlorine - To measures total residual chlorine (free residual chlorine plus mono-, di- and trichloramines) an additional reagent is used. By adding potassium iodide to the sample, chloramines in the sample oxidize iodide to iodine, which then oxidizes the DPD indicator to the magenta colour at a buffered pH of 5.1.
