Buy your Water Hardness Test Kit.

Test the hardness of your water. Essential when configuring a water softener to determine the level of hardness in the incoming water supply or check existing softener performance.

Up to 100 tests in one bottle!

Simply add the drops to a 10ml sample in the tube, each drop counts for 20ppm of hardness. Add the drops, shaking after each is added, until the colour changes from red to blue. Multiply the number of drops by 20 to get the total hardness in ppm (parts per million) or mg/l (milligrams per litre).

Useful for testing the performance of existing softeners.
