2. Function and operation
2.1 Warnings:
•This handheld meter is not waterproof, so by usage take care of water in the handheld
meter. Let the handheld meter not left in water. Water can cause damage onto the
electronic circuits.
•After using the cuvettes take care the cuvettes are cleaned properly and rinsed with water,
after rinsing they have to be dried.
•Replace the cuvettes back into the hand case so these cuvettes cannot damage. (Damage of
cuvettes cause problems with measurements).
2.2 Technical specifications :
The power for this instrument is made by 3 batteries type AA 1,5V 2500 mAh.
2.3 Performance:
The handheld meter guarantees a high quality, so take care of this meter with highest
responsibility.
With those batteries can be measured for approximately 300 hours continuously.
2.4 Surrounding influence :
During measurements the results can have influence of light so by every measurement you
have to use the 2 caps to close the cuvettes.
During the measurement of pH you have to take care of temperature disturbing. With the pH
measurement made by phenol red the temperature correction is standard at 25ºC.

5. To start
5.1 Demand of surrounding:
During measurement the results can have bad influence of light so you use 2 caps to cover the
cuvettes during measurement.
5.2 Installation:
Take the handheld meter out of case and check the cuvettes.
5.3 Cleaning cuvettes:
Before every measurement the cuvettes has to be cleaned. The cuvettes you use has to be clean not
polluted and clear. If not, clean cuvettes properly in- and outside has to be dried.
Pollution in cuvettes can cause disturbance of measurements.

7. Use
7.1 Zero calibration:
•Before every measurement a zero calibration has to be done.
•You take 2 empty, clean cuvettes (Glass test tubes) with the appropriate colour line and
rinse off with the measured water.
•Fill these cuvettes with measurement water (Blanc or control).
•Dry the cuvettes on the outside.
•Place both cuvettes in each channel.
•Activate handheld meter by pushing button “On/Off”
•Select by button “menu” the parameter you want to measure and confirm by pushing
button “enter”
•Display shows a number.
•By pushing button “calib.” you confirm the zero calibration.
•Take care, after zero calibration the number in display has to be 0.00.
If so, the zero calibration is done correct.
•When you have a correct zero calibration you can continue your sample measurements.
7.2 Free available chlorine (Cuvette with red line):
After zero calibration you can continue your sample measurement.
The cuvette for Blanc measurement is left in channel 1 (Reference).
The other cuvette must be empty and fill successively this cuvette with:
-5 drops “Start”
-5 drops “DPD 1”
-The cuvette must be filled up to the first line in the cuvette with sampling water.
(First line seen from bottom of cuvette).
-Dry the cuvettes on the outside.
-Put the cuvette into channel 2 (Measuring channel).
Read the value from display within 10 seconds and write value down.
7.3 Total chlorine (Cuvette with yellow line):
•After measuring free chlorine you can start measurement of total chlorine.
•Rinse the cuvette with the yellow line with the measured water.
•Fill the cuvette with the yellow line with:
- 5 drops “Totaal 2”
- Pour just measured solution (Pink) from free available into this cuvette.
-Dry the cuvette on the outside.
- Put the cuvette in channel 2 again.
•Read the value from display within 2 minutes and write value down.
When the “Totaal 2”has a yellowish colour, don’t use them anymore.
Suggestion, wrap the bottle in aluminium foil.
Take care of time, also for this measurement you have to wait for 2 minutes.
Use just 1 cuvette ( Always the same cuvette) to fill with “Totaal 2”. This reagent leave
Potassium Iodide in cuvette what can affect your free available chlorine measurement.

After finishing all measurements for total chlorine, the cuvettes has to be cleaned properly.
7.4 pH (Cuvette with blue line):
After zero calibration you can continue your sample measurement.
The cuvette for blanc measurement is left in channel 1 (Reference).
Rinse the blue marked cuvette with the measured water.
Fill the supplied graduated cylinder with 25 ml sample water ( pict. 1 )
Take with the pipette 0.5 ml Phenol Red liquid out of the 100 ml bottle Phenol Red ( pict.2)
Add this 0.5 ml Phenol Red to the sample water in the graduated cylinder ( pict.3)
Put the cap on the graduated cylinder ( pict. 4)
Shake the graduated cylinder gently 3x upside down for a proper mixing ( pict.5)
Fill the blue marked cuvette :
-up to the first line with the water from the graduated cylinder (First line seen from the
bottom cuvette) ( pict. 6)
-Dry the cuvette on the outside.
Put the cuvette into channel 2 (Measuring channel).
The display shows the pH, wait until this value is stable and make note of this..

When 3 horizontal stripes are shown in display, the measurement is out of range. By the colour of
sampling water it easy to see if your sample is in pH too high or too low.
Pink pH 8,0 or higher
Yellow pH 6,8 or lower.
Important :
When the display shows a pH of 8.0 and or 6.8, the measurement is not reliable anymore.
Please use a pH electrode to measure the correct pH.
