HOW TO USE
Instructions for using the TESTER Chlorine
- Remove the lid (see picture 1) and rinse out the compartments with the swimming pool water to be tested.
- 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.
- 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”).
- 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”).
- Replace the lid of the TESTER with the arrows pointing towards to printed front.
- The tablets will quickly disintegrate. Invert the TESTER several times to mix the contents thoroughly.
- 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.
- The value on the left is the pH value.
- 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.
