5. Connect the reference electrode being tested to J2 by turning the
6. Connect the new reference electrode to J2 by turning the electrode at
7. Immerse both reference electrodes in a saturated solution of KCl.
8. When the pH reading has stabilized, calculate the difference in
For most applications, a difference of less than 50 mV is satisfactory.
Therefore, the electrode can still be considered acceptable if the voltage
difference is less than 50 mV. If the difference is greater than 50 mV, try
regenerating the electrode by soaking it in a solution of 1M KCl plus 1M
HCl. If this does not reduce the potential shift, replace the electrode.
