Measure the KH value at laboratory level
Our KH test is used for the highly precise determination of carbonate hardness/alkalinity in sea water and is characterized by a high accuracy of 0.1 °dKH. The test is also very efficient; at 10 °dKH at least 100 measurements can be carried out. 100 ml of multi-reference solution is included for control purposes. This multi-reference solution can also be used to check other water parameters (e.g. salinity, calcium, magnesium, etc.).
Controlled Security
The production of our water care products is subject to strict monitoring by our own laboratory. Quality assurance helps us to select the purest raw materials and results in a top-quality end product. The measurement accuracy of the KH test was also adjusted and tested in our laboratory.
