Nitrate Pro Test Kit Red Sea

Instructions:

1. Using the supplied syringe, inject exactly 16 ml of water to be tested in one of the glass ampoules.

2. Insert one of the ampoules (control amp) into the outer hole of the comparator.

3. Shake the Nitrate Pro Reagent A bottle for 30 seconds and add 8 drops in the second ampoule (reaction amp). Close the amp with the cap

and shake for 15 seconds.

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

5. Add 5 drops of Nitrate Pro Reagent C, close the amp with the cap and stir slowly for 15 seconds.

6. Remove the cap from the reaction amp and insert it into the central hole of the comparator.

7. Wait 9 minutes until the color stabilization in the reaction amp at the end point.

8. Once the test is finished, look in the 2 ampoules from above and rotate the colored disc until the two ampoules have a similar color. Note: A numbness or excessive coloring of the water sample (organic load

high) can alter colors.

9. The nitrate level corresponding to the selected color is printed on the colored disk as indicated by the index on the side of the body of the comparator. If necessary, estimate an average value.

10. The color in the reaction amp will remain stable for 5 minutes. Do not consider the color in the amp spent this time lasso.

High range: for nitrate levels above 4ppm, dilute 1 ml of water to be tested with 15ml of RO water.
