The Aqua-check meter comes with one test-bottle

Nitrate

Manual pdf The nitrate (NO3-) package includes:

  • injector (range 0.2 to 1.0 ml)
  • 1 test bottle (empty)
  • 1 stick, with a big spoon on one end, and a small spoon on the other end
  • test-powder R1 (grey powder, small quantity)
  • test-powder R2 (white powder, larger quantity)


For testing water in the range of 6 to 30 mg nitrate per litre water:

1) Fill up 2 test bottles (A and B) with the test-water up to the marked level (at 75% of total volume)

2) Add 2 flattened small spoons of the grey powder (R1) to one of the bottles (bottle A). Screw the lid on. Shake the bottle until the powder has dissolved totally. Leave the bottle for 2 minutes.

3) Add 1 flattened big spoon of the white powder (R2) to the same bottle (bottle A) Screw the lid on. Shake the bottle until the powder has dissolved totally.

4) Use the AquaCheck to measure the nitrate level in bottle A, exactly 6 minutes after having added powder R2 (in step 3).

5) Use the AquaCheck to measure the nitrate level in control bottle B.


If the resulting nitrate level was above 30 mg / L, then repeat the test, but this time with distilled water added. For testing water in the range of 30 to 120 mg nitrate per litre water:

1) Fill up 2 test bottles (A and B) with 5 ml test-water each. Use the injector to suck up 1.0 ml of test water, and inject the water into bottle A. Repeat 5 times, so that bottle A will contain 5 ml of test water. Do the same for bottle B.

2) Add distilled water (or nitrate-free bottled water) to both bottles (A and B) up to the marked level (at 75% of total volume)

3) Add 2 flattened small spoons of the grey powder (R1) to one of the bottles (bottle A). Screw the lid on. Shake the bottle until the powder has dissolved totally. Leave the bottle for 2 minutes.

4) Add 1 flattened big spoon of the white powder (R2) to the same bottle (bottle A) Screw the lid on. Shake the bottle until the powder has dissolved totally.

5) Use the AquaCheck to measure the nitrate level in bottle A, exactly 6 minutes after having added powder R2 (in step 4).

6) Use the AquaCheck to measure the nitrate level in control bottle B.

7) Multiply the test results by 4. So if the AquaCheck indicates a nitrate level of 20 mg / L, the actual result is 4 times 20 = 80 mg / L

Phosphate

The phosphate (PO43-) package includes:

  • 1 test bottle (empty)
  • test-fluid R1 (1 full bottle, plus 1 partially filled)
  • test-fluid R2 (50 small flacons)


1) Fill up 2 test bottles (A and B) with the test-water up to the marked level (at 75% of total volume)

2) Add 9 drops of fluid R1 to one of the bottles (bottle A). Screw the lid on. Shake the bottle until the fluids have mixed.

3) Empty 1 flacon of fluid R2 into the mixture (bottle A) Screw the lid on. Shake the bottle until the fluids have mixed. Start measuring the phosphate level exactly 5 minutes after the fluids have been mixed.

4) Use the AquaCheck to measure the phosphate level in bottle A.

5) Use the AquaCheck to measure the phosphate level in the control bottle B.

Ammonium

The ammonium (NH4+) package includes:

  • injector (range 0.2 to 1.0 ml)
  • 1 test bottle (empty)
  • 1 stick, with a big spoon on one end, and a small spoon on the other end
  • test-fluid R1 (50 small flacons, colorless liquid)
  • test-powder R2 (white powder, larger quantity)
  • test-fluid R3 (50 small flacons, brown liquid)


For fresh (sweet) water:

1) Fill up 2 test bottles (A and B) with 16 ml test-water up to the marked level (at 75% of total volume)

2) Empty 1 flacon of fluid R1 into one of the bottles (bottle A) Screw the lid on. Shake the bottle until the fluids have mixed.

3) Add 1 flattened big spoon of the white powder (R2) to the same bottle (bottle A) Screw the lid on. Shake the bottle until the powder has dissolved totally. Leave the bottle for 5 minutes.

4) Empty 1 flacon of fluid R3 into the same bottle (bottle A) Screw the lid on. Shake the bottle until the fluids have mixed. Leave the bottle for 7 minutes.

5) Use the AquaCheck to measure the ammonium level in bottle A.

6) Use the AquaCheck to measure the ammonium level in the control bottle B.


For water with 7 ppt salinity:

1) Fill up 2 test bottles (A and B) with the test-water up to the marked level (at 75% of total volume) Then use the injector to suck up 1 ml and remove it from test bottle A. Repeat this 3 more times, until in total 4 ml has been removed, leaving 16 ml of test-water. Do the same for bottle B.

2) Add 4 ml of distilled water, or bottled drinking water to bottle A. Do the same for bottle B.

3) Empty 1 flacon of fluid R1 into one of the bottles (bottle A) Screw the lid on. Shake the bottle until the fluids have mixed.

4) Add 1 flattened big spoon of the white powder (R2) to the same bottle (bottle A) Screw the lid on. Shake the bottle until the powder has dissolved totally. Leave the bottle for 5 minutes.

5) Empty 1 flacon of fluid R3 into the same bottle (bottle A) Screw the lid on. Shake the bottle until the fluids have mixed. Leave the bottle for 7 minutes.

6) Use the AquaCheck to measure the ammonium level in bottle A.

7) Use the AquaCheck to measure the ammonium level in the control bottle B.

8) Multiply the results with 1.25 for the actual ammonium levels. (For example: if the result was 1 mg/L, the actual result is 1.25 mg/L)
