The feasibility of a metal palladium electrode as the pH sensor in air‐saturated aqueous solutions was evaluated. The measurement was based on an “on‐site” precleaning step and a potential decay process. The experimental results showed a linear pH response with a sensitivity of around 60 mV/pH and good reproducibiliry. The temperature effect on the measurement was also evaluated.
