Water Hardness Test Kit


Our Water Hardness Test Kits are an easy to use, reliable way to measure the total hardness of your water. The test gives a total hardness reading in mg/l (ppm) which is used to determine whether water treatment is necessary. Readings above 100ppm indicate hard water, which can be effectively treated with a water softener to prevent harmful limescale build up in appliances and pipework.

Why Choose Our Water Hardness Test Kits?

  • Easy to use test to establish an accurate water hardness reading
  • Uses a renowned reagent testing method
  • Includes full instructions for use
  • Gives reading in mg/l or ppm

Water Hardness Test Kits come with everything you need to determine water hardness. This includes reagent solution, colour-change droplets and water sample tube. The test is carried out by taking a sample of your water, before adding the reagent solution drop-by-drop to change the colour of the water. The amount of drops required to change the colour of the water is then used to calculate your water hardness. This reading can then be used to program the valve of your water softener, which determines when and how often the unit will regenerate. It can also be used to establish whether or not existing treatment is working correctly.

Full instructions on how to carry out the test are available on the test kits packaging. For a short breakdown of hardness readings please see the specification tab for more information, or get in touch with a member of our team.
