Procedure for NO₂- measurement

Before you start take into account the following:

• Use sunlight or lamp as the source of light to match the color with the color comparator box.
• Multiply the testing results by 1.5 to record the testing results as mg/L NaNO₂.
• Multiply the testing results by 0.3 to record the testing results as mg/L N.

Testing procedure

For determination of nitrite in the range between 0 and 80 mg/L NO₂-, fill two tubes to the 5 mL line with sample. Install the first tube into the left opening of the color comparator box. Add NitriVer 2 Reagent Powder Pillow to the second tube, install the stopper and shake to mix. Wait 5 minutes till the green-brown color appears. Insert the second tube into the color comparator box analyze the sample.
