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.

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.)
Order Information
Hach Ultra Low Range CL17sc Colorimetric Chlorine Analyzers are shipped with an installation kit, user manual, and one month of reagents where noted. The user selects a standpipe installation kit or a pressure regulator installation kit at the time of purchase. Hach SC controllers are required for operation and are sold separately.
