Water Hardness Test Kit – Accurate & Easy-to-Use

Our Water Hardness Test Kits provide everything you need to quickly measure the hardness of your water. Each kit includes a colour-change reagent solution and a sample tube, allowing you to test water hardness at home with ease.

Simply collect a water sample and add the reagent solution drop by drop. The water will change colour from pink to blue—count the number of drops required to determine your water hardness level. The result can be used to set up a water softener, check that it’s operating correctly, or assess whether further water treatment is required.

Full step-by-step instructions are included on the packaging.
