Nitrite Profi Test

Instructions:

1. With the syringe, add 1 ml of water in the test vial.
2. Add 1 level spoon of the NO2 powder. Swirl the contents of the test tube gently for 20 seconds. Allow to stand 3 minutes.
3. Place the open test vial on top of the color chart on a white part of the chart and compare the colors, looking from the top. Read the corresponding 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.

After your aquarium or garden pond has cycled, you will need a much higher sensitivity. This is easily accomplished by looking through the side when comparing colors. Hold the test tube with its side against a white piece of the color chart. Divide the readings by 10, which will easily detect the 0.01 ppm as nitrite or 0.003 ppm as nitrite-nitrogen.
