Assessment of the measurement value relative to the ideal range defined by you.
Measurement value for this parameter is outside the value range of this method.
Note(s)
-> (*) Special accessories required / not included as standard equipment!
-> (**) Conversion to P, P O
-> (***) Filter process is only needed in case of any suspended insoluble
phosphate expected in your water sample (applicable for boiler water
testing)
-> With this procedure ortho-phosphate ions are detected. Other phosphates
must therefore be converted to ortho-phosphates before the test is begun.
-> The pH value of the sample water should be between 6 and 7 pH.
-> The following contents of substances in the sample water can - at the
respective concentration - falsify the measurement results:
Chromium > 100 mg/l
Copper > 10 mg/l
Iron > 100 mg/l
