WebbThe pH scale is defined by the equation: pH = pHs + ( E – ES) / k, in which E and ES are the measured potentials where the galvanic cell contains the solution under test, represented by pH, and the appropriate Buffer Solution for Standardization, represented by pHs, respectively. The value of k is the change in potential per unit change in pH ... Webb30 aug. 2015 · The slope is displayed in a percentage (%) value, with 100% being ideal. When the electrode is new, the slope should be in the upper 90% range. As the electrode ages and loses efficiency, the slope and response of the electrode will start to decrease. The slope value is updated each time a two point calibration is performed and usually …
