    Actually, it's oxidation-reduction potential and is a rough measure of the quantity of oxidizers in a pool and since chlorine is usually the strongest oxidizer, it's a proxy for the amount of active chlorine in the pool (not FC, when CYA is present, but more proportional to the FC/CYA ratio though also pH dependent).

    Actually it is known as oxidation / reduction potential or redox potential. It is a measure of the tendency of a chemical species to acquire electrons and thereby be reduced. But let us not get technical here.
