Getting Started:
pH and Ion Probes
XL15, 20, 25, 50 and 60 meters
The XL series meters - XL15, XL20, XL25, XL50 and XL60 - allows you to use two types of pH
electrodes: the conventional glass pH electrode and the AccuFET
field effect transistor (FET) pH electrode.
1. Carefully remove the protective cover from the end of the
electrode. Before first using your glass pH electrode, or
whenever the electrode is dry, soak it
2-4 hours in an electrode storage solution, pH 4 Buffer, or
KCl solution.
2. Remove the shorting cap on BNC connector. Connect the
combination pH electrode by plugging it into the BNC input
connector (twisting to lock in place).
If a combination electrode isn’t used, connect the indicating pH
electrode into the BNC input connector. Plug the reference
electrode into the reference pin jack. Also, install the ATC probe
into the ATC jack.
Note: Be sure to connect all probes to the
appropriate channel connectors (for example:
pH1, Ref 1 and ATC1).
Option: Connect the optional AccuFET electrode
by plugging it into the FET jack on the back meter
panel. Allow the AccuFET to warm up five minutes
before use.
Connect ion specific electrodes in the same manner
as pH electrodes.
Do not discard the BNC
shorting cap.
