A method of measuring the pH value of a test solution with a glass electrode measurement cell and simultaneously calibrating the measurement cell

摘要

In the method for measuring the pH of a solution using glass electrodes with simultaneous calibration of the electrodes, the potentials arising on the pH glass electrode and the reference electrode are processed in a pH meter having temperature compensation and electrode slope formation. The potentials from a reference electrode (4) and two pH glass electrodes (2,3), which have different internal buffers (6,7), are processed in a first (8) and a second pH meter (9). From the processed potentials, the electrode slope is formed and, simultaneously, the measured value is formed using the slope. IMAGE
