Test the water quality
Follow the steps below to check the water quality of the cold water and soft water:
Step Action Illustration / Further details ...
1
Measure the ppm or the conductivity.
1µS/cm = 0.6 ppm (physical assumption)
2
Measure the general hardness (GH).
Pour 5ml of sampled water into an analysis container
for each water type. One drop of the analysis fluid is
equivalent to 1°dH.
No. Test time
Color of test solution
1
Analysis liquid Green
2
Start of test Colorless / orange
3
End of test Green
3
Measure the carbonate hardness (KH)
Pour 5ml of sampled water into an analysis container
for each water type. One drop of the analysis fluid is
equivalent to 1°dH.
No. Test time
Color of test solution
1
Analysis liquid Orange
2
Start of test Colorless / purple
3
End of test Orange
4
Analyze the result.
The measurements must lie within the target range.
