onto the probe.
4. Slide the two white ferrules onto the probe, the narrower one on top of the
deeper, cup-shaped one.
5. Gently slide the bottom portion of the port adapter onto the probe, taking care
to orient the longer threaded section toward the top of the probe.
6. Remove the two O-rings installed in the pH port; first slide the white Teflon O-
ring onto the probe, then follow with the black 12mm port adapter O-ring.
7. Do not yet close up all the elements of the port adapter.
8. Gently insert the probe into the appropriate port (see Figures 11, 12 & 13 for
reference), allowing the O-rings to seat fully into the port.
NOTE:
The fit may be snug. Gently rotate the probe as you press it into the port to
avoid breakage.
