Hardness
Hardness Products help you measure the level of minerals like calcium and magnesium in water. Hard water can cause scale build-up in pipes, appliances, and boilers, reducing efficiency and lifespan. By testing and managing hardness, these products help keep your water systems running smoothly, protect your equipment, and ensure your water is clean and balanced for everyday use.
