Versatile: suitable for all waters (tap water, well water, drinking water and spring water). For use in the home, kitchen and garden. For determining the water hardness for: fully automatic coffee machines (to program the hardness), softening systems/water softening systems/descaling systems (to check the function and adjust residual hardness), aquarium, pond and pool.
UNBEATABLE PRICE THANKS TO MANY MEASUREMENTS: Our goal is to provide high quality products at a good price. Make the comparison, our water hardness test is the cheapest: 50 measurements at a total hardness of 25 °dH, 400 measurements at a total hardness of 3 °dH.
Precise results thanks to the proven titration process, quick and easy: fill the supplied container with sample water and add the titration liquid drop by drop until a colour change from red to green occurs. 1 drop of titration liquid corresponds to 1° German hardness (dH). For example: colour change from red to green for the 7th Drop = 7° German hardness (°dH). If the water is directly at the 1st drops of green, the water hardness is 0° German hardness (°dH).
