Installing And Maintaining Electrodes - Denver Instrument Ultrabasic Handbuch

Installing and Maintaining Electrodes

1. Remove the protective end cover
from electrode.
2. Before using your pH electrode, or
whenever the electrode is dry, soak
overnight in an electrode filling
solution, KCI solution or electrode
storage solution.
3. Remove the shorting cap on the
BNC connector. Install the electrode
by plugging it into the input
connection (push on and turn to
lock). An accessory ATC probe can
be installed in the ATC port for the
most accurate measurement.
4. Rinse and blot-dry electrodes
between each measurement (do
not wipe). Rinse electrodes with
distilled water or deionized water,
or use the next solution to be
measured.

5. Store pH electrodes in KCI solution
or electrode storage solution.
Always leave the filling hole open
when in use and closed when in
storage. Refill with filling solution
when the internal solution level
drops to 1" below fill hole.
Note: The electrode that comes
with the UltraBasic kit is gel-filled.
It has no filling solution or filling
hole.
