Notes:
1. If the water sample is cloudy, you must filter it before performing the zero calibration.
2. The temperature of the water sample should not exceed 21°C.
3. Using the Hydrazine spoon: 1 g is equivalent to one level spoon.
4. Qualitative folded filter papers for medium precipitates are recommended.
5. In order to check whether the reagent has aged (if it has been stored for a lengthy
period), perform the test as described above using tap water. If the result is above the
detection limit of 0.05 mg/l, you should only use the reagent with reservations as there
may be a major deviation in results.
