5.1.4 Use the Electrode
1.
Insert the blue BNC connector of the electrode to the BNC socket of your
pH meter while twisting clockwise until it`s locked, plug the RCA
connector into the “TEMP” sockets. Please note not to pull the cables in
case of poor contact. Please keep the connectors clean and dry.
2.
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.
3.
Unplug the blue rubber plug to maintain a smooth electrolyte flow.
4.
Stir the solution briefly to eliminate the air bubbles and in this way, a
stable measurement will be reached fast.
5.
Perform at least a two-point calibration before measuring after connecting the new electrode to
your pH meter.
6.
After using, put the electrode back into the storage bottle, twist on the bottle cap, and plug in
the refilling hole.
5.1.5 Maintenance
1.
When not in use, the electrode should be soaked in the storage bottle containing 3M KCL
soaking solution (SKU: AI1107) 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 reference solution will run low as you use the electrode. Whenever the solution level falls
to 1/2 height of the electrode, add 3M KCL solution (SKU: AI1107) to the refilling hole (unplug
the blue rubber plug) using a syringe or pipette.
3.
The electrode is only as accurate as it is clean. Always thoroughly rinse off the electrode
before and after each measurement with pure water in a container or with a wash bottle.
