Continued...
Note(s)
-> Use of this test procedure and reagent on water samples with pH value
outside of the 6.5 - 8.4 range can lead to incorrect test results. If you are not
sure we recommend a control measurement using e.g. an electronic meter
(pH 0-14).
-> High chlorine values in the sample water can lead to incorrect test results. In
this case add a small grain of the chlorine-destroying chemical sodium
thiosulfate to your sample before adding the liquid reagent.
-> Make sure the liquid reagent drops are of equal size.
-> Store the liquid reagent for best results below 10°C and above 5°C.
