Features:

The meter measures Free and Total Chlorine between 0.00 to 3.50

ppm ( mg/L ).

The measuring method is an adaptation of the USEPA Method

330.5 for waste water and Standard Method 4500-Cl G for drinking

water.

The advanced optical system is based on a special narrow band

LED lamp that allows most accurate and repeatable reading.

User friendly and powerful calibration functions are able to validate

the performance of your meter at any time.

1.00 ppm Free standard solution and 1.00 ppm Total standard

solution are included as standard accessories.

The unique optics structure enables the instrument to read with

high resolution : 0.01 ppm ( mg/L ).

Splash waterproof on the front panel.

Jumbo LCD, easy readout.

Microprocessor circuit assures maximum possible accuracy,

providing special functions and features.

Mode Selection:

Follow these steps to switch between Free and Total Chlorine

testing modes.

1) With the meter o󰀨, press and hold the HOLD button and the

REC/MAX/MIN button. While continuing to hold the HOLD and the

REC/MAX/MIN button, press the Power button. The unit will enter

the selection mode and display the current mode selected.

2) Press the TEST/CAL button to switch between Free and Total

modes.

3) Press the REC/MAX/MIN button to conrm and save the mode

into memory.

Note:

- For swimming pool applications, the Free Chlorine function is typi-

cally used.

- For industrial water applications, the Total Chlorine function is

typically used.

Calibration Procedure:

1) The meter can be calibrated under the following calibration

points:

Free Chlorine

- Zero ppm

- 1.00 ppm

Total Chlorine

- Zero ppm

- 1.00 ppm

Note: The calibration procedures for the “Total Chlorine” and the

“Free Chlorine” are independent of each other.

2) Calibration requires the following two solutions.

- Zero Chlorine standard

- 1.0 ppm standard (Free or Total)

Calibration Procedure (continued):

3) Follow the steps below to perform calibration of the zero and

1.0ppm standards

1) Open the test chamber, place the zero chlorine

standard in the chamber and close the chamber lid.

Note: Be sure the testing bottle is seated

fully and oriented correctly. The white mark

on the bottle should point towards the white

mark on the test chamber.

2) Turn on the meter. The meter will display

the current mode (Free or Total) briey then

will display CAL 0.

3) Press the Zero button. The meter will show CAL 0.00,

then start ashing TEST. Once complete, the meter will

display 0.00 ppm. (Note: this step is not part of the

calibration process, this step sets the zero point for the

meter at power up)

4) Press and hold the TEST/CAL button until CAL is

displayed on the display then release the button. Press the

TEST/CAL button again to enter the calibration function.

5) 0.00 PPM and CAL will be displayed. With the zero

chlorine standard in the chamber, press the TEST/CAL

button and CAL will begin to ash on the screen. Once

complete, 1.00 ppm and CAL will be displayed.

6) Replace the zero chlorine standard in the teat chamber

with the 1.00 ppm chlorine standard. Then press the

TEST/CAL button. CAL will begin to ash on the screen.

Once complete, the unit will display 1.00 ppm.

7) Calibration is now complete and the meter is ready

to use. (Note: It is recommended to perform the calibration

at least once per day/use)

Measuring Procedure:

Note: Be sure to selected the appropriated measurement mode

before performing a measurement. Refer to the Mode Selection.

1) Fill the testing bottle to the 10ML line with test sample.

2) Open the test chamber and place the test sample in the chamber

and close the chamber lid.

Note: Be sure the testing bottle is seated fully and oriented cor-

rectly. The white mark on the bottle should point towards the white

mark on the test chamber.

3) Turn on the meter. The meter will display the current mode (Free

or Total) briey then will display CAL 0.

4) Press the Zero button. The meter will show CAL 0.00, then start

ashing TEST. Once complete, the meter will display 0.00 ppm.

(Note: this step is not part of the calibration process, this step sets

the zero point for the sample at power up)

5) Open the test chamber and remove the testing bottle. Open the

test bottle and add the Free or Total DPD powder. Close the test

bottle and shake bottle for at least 10 seconds.

6) Wait approximately one minute, then insert the test bottle back in

to the test chamber and close the lid.

7) Press the TEST/CAL button, the display will ash TEST. Once

complete, the display will show the measurement value.

Note: After testing, you should wash the testing bottle with distiled

water.
