Note(s)
-> DPD 1 A and DPD 1 B reagent MUST be added to the vial BEFORE
water sample is added to avoid mis-readings!
-> If the sample water contains further reducing chemicals (e.g. chlorine,
activated oxygen, bromine etc.) this will also be detected and is included in
the test results.
-> When preparing the measurement procedure it is important to avoid any
ozone escaping. This is done by means of using a pipette and shaking the
sample water. The measurement procedure must be performed directly after
sampling.
-> Use of this test procedure and reagent on water samples with pH value
outside of the 4-11 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). For measuring higher ozone values please choose the respective
matching measurement procedure.
