Note(s)
-> Use of this test procedure and reagent on water samples with pH value
outside of the 5.2 - 6.8 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).
-> Depending on the salt content of your sample, the measurement result must
be manually corrected according to the following scheme:
1 molar = -0.26 pH
2 molar = -0.33 pH
3 molar = -0.31 pH
with: 1 mol of salt (NaCl) = 5.8% = 58.4 g/l
