Measure the KH value/alcalinity at laboratory level

Our KH test is used for the high-precision determination of carbonate hardness / alkalinity in seawater and is characterized by a high accuracy of 0.1 ° dKH. The test is also very productive, at 10 ° dKH at least 100 measurements can be performed. For control purposes, 100 ml multiteferenz are included. This multi-reference solution can also be used to check other water parameters (e.g., salinity, calcium, magnesium, etc.).


Controlled safety

The production of our reef care products is subject to strict monitoring by our own laboratory. The quality assurance helps us in the selection of the purest raw materials and leads to end products in best quality. The accuracy of the KH test kit was also adjusted and tested in our laboratory.
