Web10.2.4 Response time. Response time is defined as the time at which the pH concentration in a solution is changed on contact with a pH sensor and a reference electrode has reached 95% (or 90%) of the final value. The response time is reported as t95% or t90% in seconds or minutes. In many investigations, the response time of the overall ... WebWhat is reaction time?
