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 Add 1 MolyVer 1 powder pillow to the sample water in the cuvette.
8 Stir with the stirring rod for about 20 seconds until the reagent is completely dissolved.
9 Add 1 MolyVer 2 powder pillow to the sample water in the cuvette.
10 Stir with the stirring rod for about 20 seconds until the reagent is completely dissolved.
11 Add 1 MolyVer 3 powder pillow to the sample water in the cuvette.
12 Stir with the stirring rod for about 20 seconds until the reagent is completely dissolved.
13 Screw the lid back on the cuvette.
14 Gently swirl the cuvette to mix the liquid well.
15 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
16 Tap TEST to start a 05:00 minute(s) countdown.
17 After the lapse of a 05:00 minute(s) countdown the measured value is displayed.
Notes:
The following substances interfere with the measurement: Aluminium (> 50 mg/l), chromium (>
1000 mg/l), iron (> 50 mg/l), nickel (> 50 mg/l), nitrite (> 2000 mg/l as NO₂⁻; can be eliminated
by adding one sulfamic acid powder pillow to the sample).
Concentrations of > 10 mg/l copper increase the reading, if the test is not performed quickly
enough.
Highly buffered samples or samples with extreme pH levels may require pre-treatment.
