What is meant by the response time of an electrode, and why is it important?
The response time of an electrode is the length of time necessary to get a stable reading when the electrode is moved from one solution to another of different pH or temperature. Response time is dependent on the electrode type, the measuring sample, temperature, the magnitude and direction of concentration change and the presence of interfering substances. A slow response time can be indicative of the incorrect selection of electrode for the intended application.
