A simple to use at home hard water test kit that comes complete with reagent and handy test tube in handy storage box. The water hard­ness level is measured by adding the reagent one drop at a time to a sample of your tap water until it changes colour. The hard­ness is then calcu­lated by counting the number of drops used. The results can then be used for confirming the hardness of your local tap water, setting up a water soft­ener or water filtra­tion system. Each kit is supplied with enough reagent for multiple tests.
