Lovibond 155235 Pooltester Copper-pH-Active oxygen

HOW TO USE

Instructions for using the TESTER Chlorine

1. Remove the lid (see picture 1) and rinse out the compartments with the swimming pool water to be tested.
2. Fill all compartments to the top with the swimming pool water to be analysed. This is conveniently done by scooping up the water from a few inches below the surface.
3. Press a PHENOLRED tablet out of the strip so that it drops directly into the left-hand chamber (see Fig. 2). Do not touch the tablet with the fingers (see “Important”).
4. Press a DPD No. 1 tablet out of the strip so that it drops directly into the right-hand chamber (see Fig. 2). Do not touch the tablet with the fingers (see “Important”).
5. Replace the lid of the TESTER with the arrows pointing towards to printed front.
6. The tablets will quickly disintegrate. Invert the TESTER several times to mix the contents thoroughly.
7. Take the readings by holding the TESTER towards natural daylight. Select the nearest colour match against the colour standards and read off the corresponding values.
8. The value on the left is the pH value.
9. The value on the right is the concentration of free chlorine (mg/l).

Important

• Touching the tablets with your fingers can lead to inaccurate results.
• The colour matching must be carried out immediately after the tablets have dissolved in the water sample.
• After each measurement, the TESTER and lid should be thoroughly rinsed out to prevent errors by cross-contamination.
• Levels of chlorine above 10 mg/l can cause bleaching of the DPD colour.
• pH values below 6.8 also produce a yellow colouration, so a reading of 6.8 may be incorrect. pH values above 8.2 also produce a red colouration, so a reading of 8.2 may be incorrect.
• Water samples with low values of Total Alkalinity may give wrong pH readings.

Caution

• The reagent tablets are only to be used for chemical analysis.
• They must not be used for any other purpose. Keep out of reach of children.
