If the pH electrode should dry out, soak
the electrode up to 2 hours in pH buffer
4.0 solution. If the electrode is left dry
from an extended period of time,
permanent damage will result.
pH Electrode Replacement
The pH electrode can be replaced with
the replacement electrode available from
NEWPORT Engineering (part number
PHE-8200).
To remove the electrode, simply unscrew
it clockwise from the electrode pivot
hinge on the meter. You will hear a pop;
that’s OK. Refer to Figure 4.
Figure 4. How to Unscrew the
pH Electrode
To install a new electrode, attach the
connector ends and screw counter-
clockwise or to the right until you have a
good connection.
