Note(s)
-> Alkalinity of more than 250 mg/l CaCO affect the measurement and the
color development. Neutralize to pH 6-7 with 1 N Hydrochloric Acid before
performing the test.
-> Acidity of more than 150 mg/l CaCO affect the measurement and the color
development. Neutralize to pH 6-7 with 1 N Sodium Hydroxide before
performing the test.
-> Bromine at all levels, Ozone (if >1.5 mg/l) and chlorine (if >6 mg/l) as well as
iodine will interfere with the reagent reaction and will be part of the displayed
value. Peroxides may interfere as well.
-> Organic chloramines may interfere. Monochloramines lead to higher
readings (~0.1 mg/l at 3 mg/l monochloramines after 1 minute).
-> If oxidized manganese or oxidized chromium is present in the sample,
sample needs to be pre-treated.
-> Hardness levels above 1000 mg/l CaCO affect the measurement
-> Extreme pH-values of the sample need to be corrected to pH 6-7 before
measuring the sample.
