Description
Water Total Hardness Test Tablets – 250 Tablets
Water Total Hardness test tablets are precision water hardness testing reagents designed to determine the total hardness of water, expressed as calcium carbonate (CaCO₃). The tablets react with calcium (Ca²⁺) and magnesium (Mg²⁺) ions, providing reliable and repeatable results for routine water quality monitoring.
Bidchem supplies Water Total Hardness test tablets in packs of 250, supporting laboratories, water treatment facilities, and industrial operations throughout South Africa.

How Water Total Hardness Test Tablets Work
-
Collect a measured water sample (typically 50–100 mL).
-
Add tablets sequentially while mixing.
-
Observe the color change caused by reaction with calcium and magnesium ions.
-
Calculate total hardness based on the number of tablets used.
This method ensures consistent and repeatable water total hardness measurements in both field and laboratory conditions.
