TPSMDA-PH
A pH controller works based on measurement and control principles. For measurement, it uses a pH electrode with a glass-membrane and a reference electrode. The glass membrane exchanges ion switch hydrogen ions in the solution, generating a potential difference related to the hydrogen ion concentration (following the Nernst equation). The controller processes this signal and converts it to a pH value, with temperature compensation if needed. For control, users set a target pH value. The controller compares the measured pH with the target, calculates the deviation, and if the pH is too high(alkaline), it signals to add acid; if too low (acidic), it signals to add alkali. It continuously monitors and adjusts to keep the pH near the target value in a feedback loop.
