TM KH-/Alkalinity Test Professional

The carbonate hardness (KH) or alkalinity of a water sample characterizes the buffering capacity, i.e. the ability to maintain the pH value of the water. In water chemistry there are several terms used to describe the buffering capacity with different definitions. In aquaristics the term "carbonate hardness" is commonly used, but alkalinity is measured. In this test both terms are used synonymously. The carbonate hardness is usually given in degrees of German hardness (°dH). The Tropic Marin® KH/Alkalinity-Test Professional allows you to determine the carbonate hardness of your aquarium water with an accuracy of 0.1 °dH by titration. The easily recognizable color change is from turquoise blue to pink.
