Note(s)
-> Waste and sea water must be distilled before testing.
-> Chlorine contents exceeding 5 mg/l can falsify the result.
-> In order to achieve precise test results water samples with a high fluoride
content should be diluted before testing. The most precise values are
achieved in the range of 1.2 mg/l. When diluting the water sample the result
must, of course, be multiplied by the dilution factor!
