CALCULATORS
Calculate the Ryznar index of your water
The Ryznar stability index (RSI) shows whether water tends to form calcium carbonate scale or to corrode pipes and equipment. It complements the Langelier index and is widely used in water networks, boilers and cooling circuits. Enter your analysis data to get the index and its interpretation instantly.
Indicative result. For a diagnosis of your installation, measure continuously or contact us.

How it is calculated
- Ryznar stability index: RSI = 2·pHs − pH. Below 6: scale-forming; 6 to 7: balanced; above 7: corrosive.
Measure these data continuously
With our IoT probes, sensors and equipment you have the data in real time on any device, and the panel calculates this value on its own and warns you before problems appear.
