CALCULATORS
Calculate the Larson-Skold index
The Larson-Skold index relates chloride and sulphate to the alkalinity of the water and estimates its corrosivity towards steel and cast iron. It is useful for process water, cooling water and distribution networks with metal pipes.
Indicative result. For a diagnosis of your installation, measure continuously or contact us.

How it is calculated
- Larson-Skold index: (Cl⁻ + SO₄²⁻)/alkalinity in meq/L. Above 0.8: steel corrosion possible; above 1.2: high. Chloride and sulphate estimated from conductivity.
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.
