4. Match the colour of the sample with the colour chart by positioning the test tube next the most similar colour. For accurate readings compare the colours from above.
CAUTION: do not use an excessive quantity of reagent 1 as it could alter the reaction and test results. If the quantity of nitrates in the water exceeds 25 mg/l, it is utmost importance to chenge a small amount of the water and to use a specific product such as PRODAC's AMMONIA CONTROL. Thoroughly clean the test tube after use, securely seal all reagent containers and store in a cool, dry place away from sunlight. Keep the product out of reach of children.
