Measurement procedure:
1 Fill 10 ml test water into a clean 24 mm cuvette.
2 Screw the lid back on the cuvette.
3 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
4 Start ZERO measurement.
5 Remove the cuvette again.
6 Unscrew the lid from the cuvette.
7 Empty the cuvette to a few drops.
8 Add 3 drop(s) of PL DPD 1 A into the cuvette.
9 Add 3 drop(s) of PL DPD 1 B into the cuvette.
10 Fill the cuvette to 10 ml with the sample water.
11 Screw the lid back on the cuvette.
12 Gently swirl the cuvette to mix the liquid well.
13 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
14 Tap TEST to perform the measurement.
15 The measured value is immediately displayed.
Notes:
DPD 1 A and DPD 1 B reagent MUST be added to the vial BEFORE water sample is added to
avoid misreadings!
Shake the liquid reagent thoroughly before adding the liquid to the vial.
Liquid reagents should be stored at temperatures of 5 - 10 °C in securely closed bottles.
If the sample water contains more than 60 mg/l iodine, a measured value of 0 mg/l can be
displayed. In that case, a dilution is recommended.
If the sample water contains further oxidizing agents, these will react like iodine and contribute
to the measurement result.
