3. Rinse and blot-dry (don't wipe) electrodes between each
measurement. Rinse electrodes with distilled or deionized
water, or a portion of the next solution to be measured.
4. Between measurements, store conventional
pH electrodes in electrode storage solution,
pH 4 buffer, or KCl 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.
Store ion specific electrodes according to electrode
manufacturer’s recommendations.
Proper electrode care is fundamental to 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.
