"Do you need reliable, real-time chlorine analysis to optimize your disinfection process or to report to regulatory agencies? The industry standard Hach CL17 Chlorine Analyzer uses colorimetric DPD chemistry to continuously monitor water for free or total chlorine. For typical use, the CL17 will operate unattended for 30 days and is compliant with US EPA regulation 40 CFR 140.74. Monthly routine maintenance for the CL17 can be performed in 15 minutes, including changing reagents and cleaning the colorimetric cell. No special tools are required. Are you looking for a solution that can be trusted across a wide range of sample conditions? The CL17 analysis method is not affected by changes in chlorine concentration, sample pH, temperature, flow, or pressure, thus offering more reliable and accurate measurement with less operator interventions than other methods in today's market. Do you need an online analyzer that is also capable of measuring permanganate? The CL17 is also suitable for permanganate residual measurements. Laboratory and field studies demonstrate the analytical capabilities of the analyzer to determine permanganate concentration in water and confirm that it is a robust solution and a good tool for the control of challenging water treatment processes (variable water quality and demand).*This product has not been evaluated to test for chlorine and chloramines in medical applications in the United States."
