Measurement procedure:
1 Separate the two halves of the filter holder.
2 Insert a 25 mm (GF/C) filter. Screw the filter holder back together, making sure that the O-ring
is correctly seated.
3 Fill a clean 20 ml syringe with 14 ml sample water.
4 Connect the syringe to the filter holder.
5 Empty the syringe with the filter up to the 10 ml mark.
6 Fill the remaining 10 ml filtered sample water into a clean 24 mm cuvette.
7 Screw the lid back on the cuvette.
8 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
9 Start ZERO measurement.
10 Remove the cuvette again.
11 Unscrew the lid from the cuvette.
12 Add 25 (~ 1 ml) drop(s) of PL Phosphate HR 1 into the cuvette.
13 Add 25 (~ 1 ml) drop(s) of PL Phosphate HR 2 into the cuvette.
14 Screw the lid back on the cuvette.
15 Gently swirl the cuvette to mix the liquid well.
16 Insert the cuvette into the PrimeLab. Pay attention to the arrow on the front of the cuvette.
17 Tap TEST to perform the measurement.
18 After the lapse of a 10:00 minute(s) countdown the measured value is displayed.
Notes:
Special accessories required / not included as standard equipment!
The test result can be converted into the following unit(s): mg/l P, mg/l P₂O₅.
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/phosphonates must
therefore be converted into ortho-phosphates before the test is begun.
