1. Add with the syringe 1 ml of water in the test vial. 2. Add to this 1 level spoon of the NO2 powder. Swirl the contents of the test tube gently for 20 seconds. Allow to stand for 3 minutes. 3. Place the open test vial on top of the color chart on a part of the chart that is white and compare the colors looking from the top. Read the corresponding nitrite content. An intermediate color corresponds to an intermediate nitrite content.
The nitrite values are in ppm nitrite. If you prefer a reading in ppm Nitrite-Nitrogen, then multiply the reading by 0.3.
