3. Rinse and blot-dry (don’t wipe)
electrodes between each
measurement.
Rinse electrodes
with distilled or deionized water,
or a portion of the next solution
to be measured.
4. Between measurements, store
conventional pH electrodes
storage solution, pH 4 buffer, or
KCI solution. Always leave the
filling hole of liquid filled
combination electrodes open.
Refill when the level of
solution gets below the
manufacturer’s recommended
level.
Proper electrode care is fundamental to obtaining reliable pH
measurements. Improper care of the electrode may cause the meter
reading to drift, respond slowly, or produce erroneous readings. For
this reason, the electrode should always be conditional and used in
accordance with manufacturer’s instructions.
