Hardness, total with powder

0 - 60 mg/l CaCO3 Mark as favourite

The hardness of water is a measure of its soap-consuming capacity; in practice it corresponds to the calcium and magnesium salts. Boilers usually require feed water of low hardness not only to avoid scale formation on heat transfer surfaces but also to minimise the formation of suspended solids or sludge in the boilers.
Hardness salts are not normally removed from potable water where, in the UK, their concentration can vary dramatically depending on the type of rock strata/run-off surface the water comes into contact with.
