Total hardness is a measure of the concentration of magnesium and calcium in a sample. Hardness in water is primarily caused by magnesium and calcium salts being dissolved by runoff water as it flows through different layers of rock. It is important to monitor the hardness in water as high levels of hardness can result in scaling of pipes, particularly in cooling and heating systems.

 

Hardness can be measured as calcium hardness, magnesium hardness or total hardness. Hanna offer a wide range of instruments, from Chemical Test Kits to Photometers that are ideal for measuring hardness levels.
