CL17SC/CL17DSC Online free and total chlorine analyzer

Measuring method:

The CL17sc/CL17Dsc online free chlorine and total chlorine analyzer establishes a zero reference point by measuring the blank absorbance, compensating for the color and turbidity of the sample before measuring chlorine. Afterwards, the indicator solution and buffer are added to the sample, and the color reaction is developed by means of a magnetic stir bar. Subsequently, the colorimeter measures the absorbance through the sample, and the resulting absorbance is compared with the reference standard to obtain the measurement result. Finally, the sample chamber is refilled with new sample. The analysis cycle of the online free chlorine analyzer is approximately 2.5 minutes (standard version) / approximately 10 minutes (pipeline version).

Instrument features:

Based on the traditional reliability of online chlorine analyzers, the CL17sc online free chlorine analyzer provides automatic diagnostics and is easy to maintain. The upgrade improves the ease of use of the online free chlorine analyzer, reduces the risk of data loss, and provides more reliable information to assist decision-making.

Easy to maintain

The CL17sc online free chlorine analyzer reduces maintenance workload and shortens your routine maintenance contact time through programmable warning reminders, simplified tubing replacement, and step-by-step maintenance instructions.

Good scalability

The CL17sc online free chlorine analyzer works with the HACH SC controller platform and offers good scalability. It can be connected to an automatic chlorination pump to achieve automatic chlorination, and can also be connected to external analog and digital communication devices, allowing flexible connection of external devices.

• Comprehensive diagnostics keep operation smoother

• With upgraded functions such as flow sensors, colorimetric cell observation windows, multi-color status lights, and predictive diagnostic software, you can always know whether the online free chlorine analyzer is operating as expected.
