The Waterfresh WF-TS-1 test measures water hardness and can help you choose a water softening system. To take a measurement, fill the test tube with water up to the 5 ml mark, then add the test liquid one drop at a time.
The sample changes from clear to red, then to green. The number of drops needed for the color to change from red to green corresponds to the water hardness in French degrees.
