Test set for measuring water hardness (15 ml)

  • Test set for determining water hardness
  • Take 5 ml of water using the enclosed measuring cuvette
  • The measuring liquid is dripped into the water until the color of the liquid changes
  • The number of drops gives the water hardness in °dh (titration principle)
  • 1 drop of reagent corresponds to 1° dH at 5 ml sample volume

Test set for determining water hardness - How hard is my water?

Determine water hardness quickly and precisely with our test kit. Using the enclosed measuring cuvette, take 5 ml of water. Add the test solution drop by drop until the color changes. The number of drops corresponds to the water hardness in °dH (German degrees of hardness). One drop of reagent represents 1°dH in a 5 ml sample volume.

Scope of delivery:

  • Operating instructions: Step-by-step instructions for correctly performing the measurement.
  • Measuring container: Precise measuring cuvette for the water sample.
  • Titration liquid: 15 ml reagent solution for numerous tests.

With this test kit, you can reliably determine water hardness and thus adjust water treatment measures accordingly. Ideal for use in households, aquariums, and for monitoring water quality.

The liquid is much thicker than it used to be. It's not as easy to measure. But it ultimately serves its purpose.

It works. Just keep in mind that it doesn't last forever. So, use it and test it twice a year.

It is important to check the water hardness periodically to avoid calcification of the pipes and fittings. This is especially important when using a decalcification system, which reduces the hardness of hard water, for example 20 degrees dh, to 8 degrees German hardness.
