pH control system REGA-pH/EV

pH control system Mod. REGA-pH/EV is designed for teaching and experimental analysis of pH control processes. The system includes a stirred reactor that is filled with an acidic solution via a dosing pump. By controlling the flow of a basic solution into the reactor via another dosing pump, the pH level inside the reactor can be adjusted. Using SCADA software, users can monitor and control the process in real time from a computer.
