The Memosens pH/redox combination electrodes CPS16D, CPS76D and CPS96D from Endress+Hauser make processes more transparent. The electrodes are a combination of a pH and a redox sensor. Each of the three Memosens sensors has integrated quality control: the last eight calibrations are automatically saved in the sensor head. The additional platinum pin on the sensor shaft helps to determine the condition of the diaphragm, making it possible to predict any deterioration in sensor quality. The rH value provides information on whether a medium is oxidizing, neutral or reducing. Previously, the rH value of two individual sensors had to be calculated at two different points; the combination sensors output this value directly.
