PoolSan Pooltester
Instructions for using the PoolSan Pooltester for Copper, pH & Oxygen
1. Remove the lid (see picture 1) and rinse out the compartments with 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 approximately 30 centimetres below the surface, see picture 2.
3. Add one PHENOL RED tablet to the left hand compartment by tearing open the foil strip (see picture 3) without touching the tablet with your fingers.
4. Add one COPPER No.1 tablet to the middle compartment by tearing open the foil strip (see picture 3) without touching the tablet with your fingers.
5. Add one DPD No.4 tablet to the right hand compartment by tearing open the foil strip (see picture 3) without touching the tablet with your fingers.
6. Use the stirring rod to break down the Copper No. 1 tablet as this will not dissolve as quickly as the other two tablets.
7. Replace the lid of the Pooltester with the arrows pointing towards the printed front, see picture 4.
8. Once all of the tablets have disintegrated, invert the Pooltester several times to mix the contents thoroughly, see picture 5.
9. Take the readings by holding the Pooltester towards natural daylight. Select the nearest colour match against the colour standards and read off the corresponding values, see picture 6.
10. The value on the left is the pH value, target range between 7.0 – 7.4.
11. The value in the middle is the concentration of Copper (mg/l) which indicates the level of PooLSan, target range between 0.4 – 0.7 mg/l.
12. The value on the right is the concentration of Oxygen (mg/l), which indicates the level of PoolSan Regenerator, target range between 3.0 – 8.0 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 Pooltester and lid should be thoroughly rinsed out to prevent errors by cross contamination. Levels of Copper above the 1.0 mg/l produce a dark purple colouration, so a reading of 1.0 mg/l may be incorrect. Levels of Copper below 0.1 mg/l also produce a clear colouration, so a reading of 0.1mg/l may be incorrect.
Levels of Oxygen above 10.0mg/l produce a darker red colouration and eventually change to a yellow colour as the oxygen levels increase, so readings of 10.0mg/l or higher may be incorrect.
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.
