How to use?
- Ensure the test tube is clean.
- Take a 5 ml sample of water into the test tube.
- Add 5 drops of the reagent Ammonia 1, 5 drops of Ammonia 2 and 5 drops of Ammonia 3.
- Replace the test tube cap and shake thoroughly. Wait 10 minutes, then compare the colour of the sample to the colour scale provided. Zero ammonia is represented by a yellow colour. Any hint of green in the sample indicates the presence of ammonia in the water.
This test kit reports concentration in terms of nitrogen (NH3-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 1.21 (NH3-N).
