Do not discard the BNC shorting cap.
3.
Rinse and blot-dry (don’t wipe) electrodes between each
measurement. Rinse electrodes with distilled or deionised 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 for 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 conditioned and used in accordance with
manufacturer’s instructions.
