Langelier Saturation Index Calculator


Available in the App Store

The Langelier Saturation Index computes the Langelier Saturation Index, a calculated number, to predict the calcium carbonate stability of water to determine equilibrium. This helps you determine the scaling potential of the water. A negative LSI indicates that the water is corrosive to steel.

The app also features a short interpretation of the the LSI value, and water temperature can be entered as Fahrenheit or Celsius.
