BRITA Total Hardness Test (°GH) - Professional Products

This test will allow you to identify the total hardness of your waterprior to making your coffee or teaor simply before consuming it. The total hardness helps you determine if your water is low or not corrosive.

Instructions for use:

1. Run cold tap water for 15 seconds
2. Fill the test tube up to the 5 ml mark
3. Turn the reagent bottle upside down and hold it in this position
4. Add one drop of this reagent to the water then shake
5. Repeat this operation until a green tint appears (mix well between each drop).
6. Count all the drops needed to obtain the green tint including the first drop.

10 drops = 10° Gh.
 

The higher the number of drops required to reach a green tint, the more frequently your water will need filtering.

We remind you that a water treatment solution is not universal since each geographical area has distinct water quality. The amount of filterable water may thus vary by region.
