What is the pH meter's slope range following calibration?
The slope range of the pH meter after calibration is above 95%, and the slope of the electrode after calibration should be at least above 85% after the electrode has been used for a long time.
The calculation of the slope is related to the electrode measuring the potential of the solution you prepared.
The pH measurement only indicates the difference in pH between the standard solution and the unknown solution, and the actual measurement requires periodic calibration with standard buffer solutions. Therefore, in order to achieve consistent values, a pH scale must be established. The pH scale range is set at 0~14pH, and the value of the pH scale is determined by the pHs value of the reference buffer solution.
