A pH Controller is a laboratory or industrial device designed to monitor and automatically regulate the pH level of liquids in real-time. It works in conjunction with a pH electrode/sensor to maintain the desired acidity or alkalinity by controlling dosing pumps or valves for acid/base addition. Equipped with a digital display, programmable setpoints, and alarm features, it ensures precise and reliable pH management. Ideal for applications in water treatment, chemical processes, biotechnology, and research laboratories, the pH controller enhances process efficiency, consistency, and safety in pH-sensitive operations.
