RESULT
The result is shown in the display in mg/l Cyanuric acid.
Tolerances:
> 50 – 100 mg/l: ± 15 mg/l
> 100 – 160 mg/l: ± 20 mg/l
Notes:
1. Use deionised water or tap water free of Cyanuric acid.
2. If Cyanuric acid is present a cloudy solution will occur.
Small single particles are not necessarily caused by Cyanuric acid.
3. Dissolve the tablet completely (therefore swirl the vial approx. 1 minute).
Un-dissolved particles of the tablet can cause results that are too high.
