To measure free chlorine in water using the MACHEREY-NAGEL Visocolor ECO Chlorine 2 Test Kit, follow these steps:
1. Pour a 5 mL water sample into one of the measuring glasses using the plastic syringe and place it on position A in the comparator. Only add the reagent to measuring glass B.
2. Fill the second measuring glass with 3 drops of Cl2-1.
3. Add 3 drops of Cl2-2.
4. Add a 5 mL water sample using the plastic syringe, seal the glass, and mix.
5. Open the glass and place it on position B in the comparator.
6. Slide the comparator until the colors match in the inspection hole on top. Immediately check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
Note: The measurement reading will indicate the concentration of free chlorine in the water sample.
For total chlorine measurement (only applicable to REF 931015 / 931215), follow these additional steps:
1. Add 3 drops of Cl2-3 to the second measuring glass. Seal the glass and mix.
2. Open the glass after 2 minutes, place it on position B in the comparator, and read off the chlorine value as described above.
After use, remember to rinse out both measuring glasses thoroughly and seal them.
Please refer to the provided color chart and the instructions for use for more detailed information and guidelines.
