2. Unscrew the pH-Ag/AgCl reference electrode and remove it from the cell
body (see
Figure 9-56. Removing the pH-Ag/AgCl Reference Electrode
3. Unscrew the storage cap from the new pH-Ag/AgCl reference electrode
(see Figure
Always store the electrode in the storage cap filled with saturated KCl
solution when the cell is not in use. This prevents the pH-Ag/AgCl
reference electrode membrane from drying out and damaging the
electrode. See
Figure 9-57. pH-Ag/AgCl Reference Electrode in Storage Cap
4. Rinse the new electrode thoroughly in ASTM Type I (18 megohm-cm)
filtered and deionized water that meets the specifications listed in
Section 1.5
5. Calibrate the pH-Ag/AgCl reference electrode (see
Doc. 065342-06 12/11
Figure 9-56).
