What is a pH and ORP Controller?

A pH and ORP controller is an automated instrument used to continuously monitor and control the acidity, alkalinity, and oxidation-reduction potential of liquids. These controllers help maintain accurate process conditions by receiving signals from sensors and supporting automated control of dosing pumps, valves, alarms, and other process equipment.

• pH Value: Indicates the acidity or alkalinity of a solution. A lower pH value represents an acidic solution, while a higher pH value represents an alkaline solution. Maintaining the correct pH level is important for process efficiency, product quality, and equipment protection.
• ORP Value: Measures the oxidizing or reducing capability of a solution. A higher ORP value indicates stronger oxidizing conditions, making ORP measurement useful for water treatment, disinfection, chemical dosing, and wastewater management.
