LSI, RSI and corrosion/scale risk calculator for espresso machines. Compare with La Marzocco, SCA and Nuova Simonelli standards.
The corrosion and scaling calculator evaluates the risk your water poses to an espresso machine, using indices like the Langelier (LSI) and RSI to predict tendency to corrode metals or form limescale.
Enter the water composition (hardness, alkalinity, chloride, sulfate, sodium, TDS and temperature) and see the diagnosis against reference ranges from makers like La Marzocco and Nuova Simonelli.
This is the equipment-protection step: even water that is good for extraction can be aggressive to the boiler if the mineral balance is wrong.
It is an index showing whether water tends to dissolve metal (corrosion) or deposit calcium carbonate (scaling), based on the balance of hardness, alkalinity, pH, TDS and temperature.
Enter the composition and boiler temperature; the tool computes the indices and shows whether the risk is corrosion, limescale or a balanced water.
Manufacturers usually ask for moderate hardness and alkalinity, low chloride and controlled TDS. The tool includes reference ranges like La Marzocco, SCA and Nuova Simonelli.
Generally yes: very soft, acidic water tends to corrode, while very hard, alkaline water tends to form limescale. The goal is the balance point.
By adjusting minerals (remineralization or blending) and, when needed, filtering or softening the water until the indices are in the safe range.
