CL17sc Colorimetric


Do you need reliable, real-time chlorine analysis to optimize your disinfection process or to report to regulatory agencies?
The industry standard Hach CL17sc Colorimetric Chlorine Analyser uses colorimetric DPD chemistry to continuously monitor water for free or total chlorine. The CL17sc will operate unattended for 30 days and is compliant with US EPA regulation 40 CFR 141.74. Monthly routine maintenance for the CL17sc can be performed in a few minutes, including changing reagents and cleaning the colorimetric cell. No special tools are required, and step-by-step, on-screen instructions for all routine maintenance activities give you the confidence that you performed the task correctly without missing any key steps.

Are you looking for a solution that can be trusted across a wide range of sample conditions?
The CL17sc analysis method is not affected by changes in chlorine concentration, sample pH, temperature, flow, or pressure. This provides more reliable and accurate measurement with less operator interventions than other methods in today’s market.

Do you spend too much time troubleshooting problems with your current chlorine analyser?
The CL17sc is equipped with a comprehensive set of diagnostic features that help you prevent downtime. With a built-in flow meter, three-colour status light, measurement cycle indicators, colorimeter window, and on-screen diagnostics menu you’ll spend less time identifying and fixing issues when they arise.

Do you need an online analyser that is also capable of measuring permanganate?
The CL17sc is also suitable for permanganate residual measurements. Laboratory and field studies demonstrate the analytical capabilities of the analyser 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).
