    1.Temperature compensation

    The pH range (0-14) is determined through the ion product of the water, which to a very small extent dissociates into H+ and OH– ions. [H+ ] [OH– ] = 10–14 = I (25°C) The ion product I is strongly dependent on temperature.

    The temperature influences the pH measurement through four factors:

    • Chemical equilibria are temperature dependent

    • Temperature dependence of the slope (see Nernst equation below)

    • Position of the isothermal intersection

    • Differing response time of the electrode (caused by temperature changes).


    Every measuring solution has a characteristic temperature and pH behaviour (temperature coefficient). In general you should assume that a
    temperature change results in a pH change (see buffer/temperature
    table below). The reason for this is the temperature dependent dissociation which causes a change in the H+.
