Application of Total Hardness Test Kit

The total hardness test kit determines water hardness in German hardness degrees. Each drop added corresponds to one degree of German hardness.

Step 1

As long as the water is red, add the liquid drop by drop into the measuring cup. Count each drop and shake the measuring cup after each drop.

Step 2

As soon as the water turns slightly yellowish, carefully add one or two more drops.

Step 3

As soon as the liquid turns green, you have determined the water hardness based on the number of drops added.
