The Hach CL17 Chlorine Analyzer uses colorimetric DPD chemistry to monitor water continuously for free or total residual chlorine. The CL17 is a simple, dependable and economic solution, and the preferred choice to high-maintenance instruments that require frequent calibration. The CL17 analysis method is robust and not affected by changes in chlorine concentration, sample pH, temperature, flow, or pressure, thus offering more accuracy and reliability than alternative instruments and technologies.
Monthly routine maintenance for the CL17 can typically be performed in 15 minutes and includes changing reagents and cleaning the colorimetric cell. No special tools are required. For typical use, the CL17 will operate unattended for 30 days. Challenging applications may require more frequent cleaning.
The CL17 Chlorine Analyzer is factory calibrated. A built-in electronic calibration curve is preprogrammed into the instrument. This instrument does not require recalibration unless specified by your regulatory agency for compliance reporting purposes.
The CL17 is compliant with US EPA regulation 40 CFR 140.74, and both Method 4500-CL G and Method 334.0 can be used for measurement of residual chlorine in drinking water.
Both an alarm for manual chlorine feed control and a 4-20 mA output for automatic control of chlorine feed pumps is available on the CL17 Analyzer.
