Potassium Pro Titrator Test Kit Red Sea

Instructions on the Potassium Pro Test Kit

1. Prepare the filtering kit as follows:

a. Place a clean and dry filter paper on the stock (III)

b. Place the top cylinder (I) on the filter paper and push down, ensuring the filter paper between the cylinder and the funnel.

c. Place the filter mounted on the filter cup (IV)

2. Using the large syringe supplied, inject exactly 2 ml of water to be tested in one of the glass ampoules. 3. Add exactly 3ml of RO or distilled water in 2 ml of sample water.

4. Add 4 drops of Potassium Pro Reagent A, close the amp with the cap and shake for 15 seconds.

5. Add 11 drops of Potassium Pro Reagent B, close the amp with the cap and shake for 15 seconds.

6. Wait for 10 minutes (use chronometer) and then pour all the glass amp liquid on the filter.

7. Wait (about 7 minutes) until you collect at least 3ml of filtered liquid in its cup (top of the line), remove the filter and dissolve the remaining liquid. Using the 5ml syringe, inject exactly 3ml of liquid filtered by the filter cup into the second glass ampoule.

8. Make sure the supplied needle is located on the 1 ml titration syringe and fill with 0.5 ml of Potassium Pro Titrant (D). Note on the loading of the syringe for titration of 1ml Rinse the syringe plunger (see arrow in the diagram) until you reach the notch 1.0 ml 0.1-0.15 below the plunger. Do not try to remove the air trapped between the liquid and the plunger. This small volume of air corresponds to the liquid contained within the plastic needle.

9. Insert the syringe at the center of the titular solution so that the graduated series on the side of the syringe is visible. Gradual grades are 0.01 ml, equivalent to 3 ppm of potassium.

10. Add 2 drops of Potassium Pro Reagent C and stir slowly. The sample test will not now have the starting color of the titration as shown on the instruction card.

11. Screw the glass amp at the base of the titrant solution.

12. Add a drop per time to Potassium Pro Titrant (D) by pressing the syringe plunger and stirring slowly immediately after, until it reaches the final color. Pay special attention to the color of the sample test after adding the first drop.

Note: The amount of solution used is inversely proportional to the potassium level in the pool water sample. If the final colour is reached after the first drop, the potassium level is equal to or greater than 467 ppm. 13. Write down the amount of titolating solution used (depending on the initial and final position of the plunger, not the liquid surface) and use the table to calculate the potassium level in the water sample. 14. Unused solution Dissolve all syringes, glass ampoules and RO water filter or distilled water before putting them away. Filtering cards are used only once.
