PoolManager's

most important function is continuous measurement

That is how PoolManager

pH value
The pH value indicates whether the water is in a neutral, acidic, or
basic range. The pH scale usually ranges from pH 0 to pH 14.

PRO potentiostatic chlorine measurement directly
records the portion of free chlorine/bromine in the pool affecting
