Water Hardness Meter – Reliable Measurement of Water Hardness

Water hardness meters are essential instruments for determining the hardness level of water, primarily caused by the concentration of calcium and magnesium ions. Accurate water hardness measurement helps prevent scaling in pipes and equipment and optimizes water treatment processes.

Why water hardness meters are important:

  • Prevention of scale buildup and damage to technical systems
  • Optimization of softening and water treatment processes
  • Ensuring compliance with quality standards
  • Support for chemical dosing

The hardness of water is formed by dissolved salts. In natural waters, hardness is formed mainly from magnesium and calcium hydrogen carbonate and sulfate dissolved from the soil and / or aquifers. 

The more salts dissolved in the water, the harder the water becomes. Since the composition of the geological subsoil varies greatly from region to region, a wide variety of water hardnesses and compositions are encountered in practice.

Other input pathways include dissolution by acidic components of precipitation or by nitric acid from nitrification resulting from agricultural fertilization.
