13. Press ZERO key.
14. Removethe vial from the sample chamber.
15. Place the vial (the sample) in the sample chamber
making sure that the marks are aligned.
16. Press TEST key.
The result is shown in the display in mg/l Aluminium.
Notes:
1. Before use, clean the vials and the accessorieswith Hydrochloric acid (approx. 20%).
Rinsethem thoroughly with deionised water.
2. To get accurate results the sample temperature must be between 20°C and 25°C.
3. A low test result may be given in the presence of Fluorides and Polyphosphates.The
effect of this is generally insignificant unless the water has fluoride added artificially.
In this case,the following table should be used:
Fluoride
[mg/l F]
Displayedvalue: Aluminium [mg/l Al]
0.05 0.10 0.15 0.20 0.25 0.30
0.2 0.05 0.11 0.16 0.21 0.27 0.32
0.4 0.06 0.11 0.17 0.23 0.28 0.34
0.6 0.06 0.12 0.18 0.24 0.30 0.37
0.8 0.06 0.13 0.20 0.26 0.32 0.40
1.0 0.07 0.13 0.21 0.28 0.36 0.45
1.5 0.09 0.20 0.29 0.37 0.48 ---
Example:If the result of Aluminium determination is 0.15 mg/l Al and the Fluoride
concentration is known to be 0.4 mg/l F, the true concentration of Aluminium is
0.17 mg/l Al.
