There are two sets of reagents one for free chlorine only (HH/HPT210) and one for free and Total chlorine (HH/HPT310). Each set is suitable for approx. 100 tests and has a 12 month shelf life when sealed or a 3 months shelf life once opened.

To perform the test for free chlorine 3 drops of reagent A are added followed by 3 drops of reagent B, in the case of total chlorine 3 further drops of C are added.
