Potentiometric Ion-Selective Measurement.
(NB: Graphical display of calibration data not available on 4- or 8-channel versions.)

Results are displayed in a data table (together with date, time and calibration details) and plotted on the calibration graph (as shown in pictures below). Both of these can be printed and the table can be exported to other packages. Also displayed are the necessary values for checking the whole measurement procedure i.e.:

  • the overall slope of the calibration and the slope between adjacent points;
  • the temperature of measured solutions and calibrating solutions;
  • the pH of the solution (if a pH electrode is installed).

    • Note that the x-axis units are always the Logarithm of the Molar concentration - no matter which units have been entered during calibration.
