HF Scientific CLX OnLine Residual Chlorine Analyzer

• 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 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.

• Removable Sample Cuvette

A removable 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.

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 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.
