Does the online hardness detector measure the total amount of calcium and magnesium ions, or the total calcium and magnesium content? Does it include calcium carbonate and magnesium carbonate that have already been formed? Does anyone know?

GB/T 6989-2008 – You may want to take a look at it; it defines total water hardness as the total amount of Ca2+ and Mg2+ in water

Okay, I couldn’t find this national standard, but I found other standards. Thank you
