Total Chlorine System
A complete system designed to meet your total chlorine needs
The RosemountTM TCL total chlorine system features a complete sample conditioning system that permits a single sensor to
measure total chlorine in water. The system can also be used to measure chlorinated sea water.

Overview
A Robust Sample Conditioning System
No metal wetted parts - ideal for sea water.
Low sample flow (about 15 mL/min) minimizes sample
waste.
Reagent-based system allows true chlorine measurement.
Continuously measure total chlorine for up to two months
on five gallons of reagent.
Trusted Sensor and Transmitter
The Rosemount 1056 Dual Channel Transmitter features a
four line, back-lit display with an easy to use interface, two
independent outputs, and optional fully programmable
alarms.
The Rosemount 56 Dual Channel Transmitter features a
four line, full color display with an easy to use interface,
four fully programmable outputs and relays, HART digital
communications, and data logger.
The 499ACL-02 Total Chlorine Sensor is a robust sensor
that is easy to maintain.
Continuously measure total chlorine for up to two months
on five gallons of reagent.
How It Works
The sample conditioning system continuously injects a
solution of acetic acid and potassium iodide in the drawn
sample. The acid lowers the pH to between 3.5 and 4.5
and allows total chlorine in the sample to quantitatively
react with the potassium iodide to produce iodine. The
sensor measures the iodine concentration, and the
transmitter displays the total oxidant concentration in
ppm as Cl2.

membrane keypad. The language (English, Spanish, Italian,
Portuguese, German, French, or Chinese) used in the menu
screens shall be selectable by the user.
20. The transmitter shall have a security feature to prevent
unauthorized tampering with calibration and conguration
settings.
8. The sensor shall be a membrane-covered, two-electrode
amperometric device, having a gold cathode, silver/silver
chloride anode, and a silicone membrane.
9. Expected sensor electrolyte life shall be about four months.
10. No special tools shall be required to change the membrane
or to perform routine maintenance.
11. The sensor shall be available with a quick disconnect tting
to permit it to be replaced without removing and rewiring
the cable.
12. The transmitter shall receive the raw signal from the
sensor and automatically corrrect it for temperature
effects. Results shall be displayed as ppm Cl2. A dual input
transmitter shall also be available if the user wishes to
use a single transmitter to measure two parameters, for
example, total chlorine and pH.
13. The transmitter shall require single point calibration.
A correction for the sensor zero current shall also be
available.
21. The transmitter shall be Rosemount Model TCL with Model
1056 Transmitter and 499ACL-02 Total Chlorine Sensor or
approved equal.
