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.
Battery operated for eld and on-site testing convenience.
Data hold function for freezing the desired value on display.

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 conrm 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)
9
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) briey 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) briey 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.
