Brita Carbonate Hardness Water Test (°KH)

This test allows you to measure the carbonate hardness (limescale level) of your waterprior to preparing your coffee or teaor simply before consuming it.

Instructions for use:

1. Run cold tap water for 15 seconds
2. Fill the test tube up to the 5 ml graduation 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 yellow tint is obtained (mix well between each drop).
6. Count all the drops needed to obtain the yellow color, including the first drop.

10 drops = 10° Kh.
 

The higher the number of drops required to reach the yellow color, the more frequently your water will need filtering.

We remind you that no water treatment solution is universal, as each geographical area has specific water quality. Filtered water capacity may thus vary according to regions.
