Calcium Hardness Liquid Reagent Kit

Overview

Calcium hardness reagent kit measure calcium hardness on its own, separate from magnesium. It is the figure used in the pool water balance calculation and in scaling indices, where calcium is the ion that actually forms the carbonate scale.

Key features

• Reads calcium hardness alone, the figure used in water balance and scaling indices
• Ready-made reagent, so there is no weighing or dilution on the bench
• Supplied in the Kit size, item code PL2020CH12

Frequently asked questions

Why measure calcium hardness rather than total hardness?
Calcium is the ion that forms carbonate scale and it is what the Langelier and pool balance calculations use. Total hardness adds magnesium, which behaves differently.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
