NTLABS - Nitrite (NO2) Test Kit

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 Nitrite reagent.
• Replace the test tube cap and shake thoroughly.
• Wait 2 minutes, then compare the colour of the sample to the colour scale provided. Zero nitrite is represented by a colourless sample. Any hint of pink in the sample indicates the presence of nitrite in the water. Any colour forming after the two minutes should be ignored.
