response speed of a pH sensor

Why does the response speed of a pH sensor decrease in winter?

Blog / /

In winter, the response speed of a pH sensor decreases mainly due to the impact of low temperatures on the sensor’s electrochemical properties. Here are the specific reasons: Increased viscosity of the electrolyte: The reference electrode and glass electrode in a pH sensor contain electrolytes. In low-temperature environments, the viscosity of the electrolyte increases, which
