How to use
1. Insert the blue BNC connector of the electrode to the BNC socket of your pH
meter while twisting clockwise until it’s locked.
2. Insert the black RCA connector of the electrode to the RCA socket directly.
3. Before measuring, twist off the storage bottle cap (see graph on the right), pull
out the electrode and rinse it off with distilled or deionized water.
4. Perform at least a two-point calibration before measuring after connecting the
new electrode to your pH meter.
5. After using, put the electrode back into the storage bottle and twist on the
bottle cap.
Maintenance
1. When not in use, the electrode should be soaked in the storage bottle containing 3M KCL soaking
solution to keep the glass membrane and junction in a healthy condition. Clean the bottle and replace
the soaking solution if it gets contaminated. The electrode should never be stored in pure water such
as deionized or distilled water.
2. The electrode is only as accurate as it is clean. Always thoroughly rinse off the probe before and after
each measurement with pure water in a container or with a wash bottle.
3. The transparent polymer gel electrolyte will inflate and ooze out a bit when it’s soaked in KCL solution.
This will not affect the measurement of the electrode, and it will happen more frequently with newer
electrodes. This is a “self-clean” situation especially when the junction gets contaminated. Just wipe
off the inflated gel with clean tissue and continue to use the electrode as normal.
4. When piercing meat (especially frozen meat), avoid bending the spear tip. Wash the electrode and
the titanium sheath with soap water after measurement, the titanium blade can be screwed off and
cleaned separartely if necessary.
5. The connector of the electrode should be kept clean and dry. If contaminated, please clean it with
medical cotton and absolute alcohol and blow dry to prevent the short circuit of the electrode and
slow reaction of electrode.
6. For tough contaminants, soak the electrode in Apera cleaning solution (AI1166) for 30 minutes. Then
use a soft brush to remove the contaminants. Afterwards, soak the electrode in 3M KCL soaking
solution for at least 1 hour. Rinse it off, then re-calibrate it before using again.
