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.
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.
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).
Introducing ourselves: AGUALEVE is a medium-sized, family-run specialist company specialising in water treatment and water technology. Your satisfaction is our number one priority. If you have any questions or difficulties, please feel free to contact us at any time. We promise you to find a solution that will make you 100% satisfied.
