The acidity and amount of chlorine in the pool are monitored by pH and ORP (oxidation reduction potential) probes, respectively. When insufficient levels of either exists, the controller requests the addition of the respective chemical. Ideally, pH should be between 7.4 and 7.6. Proper pH prevents eye/skin irritation, maximizes chlorine effectiveness and minimizes corrosion. ORP should typically be between 650 mV and 750 mV for proper water disinfection. | The acidity and amount of chlorine in the pool are monitored by pH and ORP (oxidation reduction potential) probes, respectively.

While ORP is a means for verifying the level of pool chlorine, it is not a direct measurement of chlorine. ORP measures chlorine's ability to oxidize pool contaminants. | While ORP is a means for verifying the level of pool chlorine, it is not a direct measurement of chlorine.
