SINIS TDS measuring device water hardness
A total water hardness between 50ppm (or 2.9dH) and 150ppm (or 8.4dH) is recommended. You can measure the total water hardness with this digital TDS measuring device. The water hardness is shown in ppm on the display of the TDS measuring device.
If you measure values above 150ppm, i.e. your water is too hard, we strongly recommend that you filter your water (e.g. with Brita filter products), as damage to your coffee machine caused by limescale deposits is not normally covered by the machine warranty.
