Unlike ORP control, using free or total chlorine control can give precise readings of the actual hypochlorous acid or free (residual) chlorine content of the water being treated. Hypochlorous acid content fluctuates with changes in pH and regular ORP readings can give false impressions of the actual ‘effective kill’ of the chemicals being used.
