About this file
This document is a product specification sheet for the CLX OnLine Residual Chlorine Monitor manufactured by HF scientific. The device is designed for monitoring chlorine levels in drinking water, wastewater, industrial, and marine applications, utilizing colorimetric DPD chemistry technology. Key features include a rugged NEMA 4X enclosure, user-selectable cycle times between 110 seconds and 10 minutes, a removable sample cuvette, and microprocessor-based technology.
The specifications detail a measurement range of 0-10 mg/l with ±5% accuracy for 0-6 mg/l and ±10% accuracy for 6-10 mg/l. The monitor includes standard 4-20 mA and RS-485 with Modbus outputs, two user-selectable alarm relays, and operates in temperatures from 0°C to 40°C. It is certified to CE, UL, and CSA standards, with dimensions of 325.74 x 311.11 x 128.50 mm and a shipping weight of 8 lbs. The catalog number for the complete monitor is 20040, with various accessories and reagent options available separately.

Reliable Chlorine Monitoring
Specifications HF scientific developed the CLX OnLine Residual Chlorine Monitor specifically for drinking water, wastewater, industrial and marine residual chlorine monitoring applications.
The CLX OnLine Residual Chlorine Monitor is manufactured using microprocessor based technology making it the most reliable and cost efficient instrument for monitoring residual chlorine.
Colorimetric DPD chemistry technology provides a proven, stable and reliable reading along with the most economical method available.
Features
• Colorimetric DPD Chemistry
Proven reliable and economical, colorimetric DPD (N,N-diethyl-p-phenylenediamine) chemistry is the most accurate method for measuring free or total residual chlorine.
• Rugged Enclosure The CLX's small footprint and corrosion resistant NEMA 4X (IP66) enclosure allows for a simple installation that will fit in almost any space.
• Optical Design New optical design uses similar optics to the hand held portable Chlorine Photometer. The new design increases accuracy and allows for comparable and precise readings between the OnLine Monitor and hand held portable instruments.
• Removeable Sample Cuvette A removeable sample cuvette allows for simple cleaning and maintenance. Viewable sample chamber allows a clear view of the sample cuvette while the instrument is sampling.
• Cycle Times User selectable cycle times allow the user to set the cycle time from 110 seconds up to 10 minutes (optional 60 seconds to 10 minutes). Low volume reagent and sample chamber allow for affordable reagent costs and decreases water consumption.
• Certification Listed or Certified to CE, UL, CSA (ETL,ETLc)

Changing the Sample Cuvette
Sample Specifications The Residual Chlorine Monitor shall be able to measure free or total chlorine using the DPD colorimetric method. The Chlorine Monitor shall have a measurement range of 0-10 mg/l. The Chlorine Monitor shall include the power supply, sensor and display in one NEMA 4X (IP66) corrosion resistant enclosure. The Chlorine Monitor shall have readings consistent with laboratory and portable Chlorine Photometers. The Chlorine Monitor shall have standard 4-20 mA outputs and RS-485 with Modbus Protocol. The 4-20 mA output shall be standard or reversible.
The Chlorine Analyzer shall have a removable sample cuvette.
The sensor shall have a clear view to the optical chamber allowing viewing of the sample and reaction of the reagents, before, during and after a reading. Accuracy shall be ±5% with a resolution of 0.01 mg/l for the range of 0-6 mg/l and ±10% with a resolution of 0.01 mg/l for the range of 6-10 mg/l.
The Chlorine Monitor shall have a user selectable cycle time between 110 seconds and 10 minutes (optional 60 seconds to 10 minutes). The Chlorine Monitor shall be capable of 30 days of unattended operation. The Chlorine Monitor shall take a zero reading before each reading to compensate for color in the sample. The Chlorine Monitor shall have microprocessor based technology. The Monitor shall have two user selectable alarm relays.
