Cumulative Chlorine Counter™
Understand the true impact of chlorine exposure. The Ultra Low Range CL17sc allows for process control across your water cycle, including visibility into GAC exhaustion or channeling and dechlorinating agent dosage. It is the only instrument with a cumulative chlorine counter, which helps you forecast your RO membrane efficiency and its useful life.

Accuracy at Lower Range
With a limit of detection of 8 ppb, you can take control of your dechlorination process, protect your assets from chlorine damage, and meet strict residual chlorine limits.

Parts per Billion Reading
Eliminate reading confusion when process adjustments and chlorine discharge require ultra low range control.

Total chlorine confidence. From the global leader in chlorine analysis.
Meet your unique water cycle needs with the new Ultra Low Range CL17sc online total chlorine analyzer from Hach®. Whether treating utility water, product water, or wastewater discharge, you’ll have the direct chlorine measurements you need to optimize your process. You’ll be able to protect valuable assets and report to regulatory agencies with confidence.

Applications

  • Drinking Water
  • Wastewater
  • Food and Beverage
  • Pharmaceutical
  • Power
  • Semiconductor
  • Field Use

Monitor and Optimize your Dechlorination process

Chlorine breakthroughs can adversely affect your process, product, or equipment. You’ll be able to mitigate issues and optimize your process with the Hach Ultra Low Range CL17sc analyzer, which has the lowest limit of detection at less than 8 ppb. It’s time to accurately measure your total residual chlorine and take control of your dechlorination process.

Depend on direct measurements
Online residual chlorine measurement options for ultra-low range have been either inadequate or inefficient – until now. The Ultra Low Range CL17sc gives you direct total chlorine results, eliminating the need for ORP or amperometric measurement. The Ultra Low Range CL17sc uses colorimetric DPD Standard Method 4500-Cl G and consistently maintains accuracy without loss of sensitivity in your new target range.

Protect your assets
Understand the true impact of chlorine exposure. The Ultra Low Range CL17sc allows for process control across your water cycle, including visibility into GAC exhaustion or channeling and dechlorinating agent dosage. It is the only instrument with a cumulative chlorine counter, which helps you forecast your RO membrane efficiency and its useful life.

Connect with Claros
When the new Ultra Low Range CL17sc analyzer is connected to Claros™, Hach’s Water Intelligence system, it provides realtime visibility into your processes so you can optimize and automate your chlorination/dechlorination. You’ll have peace of mind and more time to focus on high-value tasks.

Principle of Operation
The Ultra Low Range CL17sc Colorimetric Chlorine Analyzer has three operating components:

  • A linear peristaltic pump to precisely control the volume of incoming samples and reagents
  • A colorimeter
  • Indicator and buffer solutions

A zero reference point is established at the beginning of the cycle by measuring blank absorbance. (This compensates for the sample’s color intensity and turbidity before the chlorine measurement is made.) Indicator and buffer solutions are then added to the sample while a magnetic stirrer mixes the solution and the sample changes color. A colorimeter then measures the light transmitted through the sample. The measured color intensity is compared to a reference standard. Finally, the sample cell is flushed with new sample so that the cycle can repeat every 2.5 minutes.

Dimensions

The Ultra Low Range CL17sc is designed to be wall-mounted with four ¼-inch screws. Adequate clearance must be left for plumbing and controller connection. The sample inlet connection is a ¼-inch quick-connect fitting and the drain connection is ½-inch ID flexible hose. The analyzer receives power from connection to a Hach SC controller. (The analyzer’s cable is approximately 6.5 ft. in length.)
