• Accurate Water Testing: Lovibond® Calcium Hardness Tablets deliver the highest level of accuracy and precision in water testing
• Handling ease: These tablets have been designed with the user's convenience in mind

Lovibond® Calcium Hardness, 250 tablets to be used in conjunction with a 50ml or 100ml shaker bottle. These tablets measure calcium hardness in mg/l. For example, add one tablet to your sample, close the stopper, and shake until the tablet dissolves. Repeat until the pink colour changes to violet.

Calcium Hardness can then be calculated as:
50ml sample container = number of tablets added multiplied by 40 then minus 20 to give you your Calcium Hardness reading. i.e. 4 tablets added, so (4 x 40) – 20 = 140 mg/l
100ml sample container = number of tablets added multiplied by 20 then minus 10 to give you your Calcium Hardness reading. i.e. 8 tablets added, so (8 x 20) – 10 = 150 mg/l
