Test sticks for the semi-quantitative determination of the carbonate hardness
Carbonate hardness is that part of the total hardness resulting from the content of alkaline earth ions, which are equivalent to the carbonate and hydrogen carbonate ions present in the water. Thus the carbonate hardness is the portion of the total hardness which contributes to the formation of alkaline earth carbonates (boiler scale).
Gradation of scale: 0-3-6-10-15-20 ░d light green to blue
Strong bases -or other acid-consuming substances cause false results. Instruction Sheet
