11.1.2 Design
The electrode housing is made of ABS. With the exception of the electrode shaft all parts need to be maintained
regularly and be replaced if necessary.
o Protective flask
: The protective flask is used to moisten the membrane. This prolongs service life of the electrode.
The protective flask contains water. Attention! Use water only; never use potassium chloride (KCI); this is only required
for storage of pH-electrode.
o Diaphragm head
: The membrane head is covered with a Teflon membrane. It will be filled with KOH electrolyte and
screwed onto the electrode shaft (no air bubbles). Damages in the membrane, large air bubbles or air bubble rings in
the membrane head will result in erroneous measurements. This may also be the reason for errors in the calibration.
The membrane head is a spare part and can be ordered individually.
o Filling hole
: If the electrode is used at high temperatures or if it has been stored without its protective flask for a
longer period of time, some electrolyte will be lost due to evaporation. Please refer to Refilling description below.
11.2 When is electrode maintenance required
Attention when working with electrolyte!
The electrolyte is caustic! (strong base, KOH)
Avoid contact with skin and eyes.
Protective equipment is necessary!
Irritates skin and mucous membranes, caustic.
In the case of contact with the eyes, immediately clean with clear water about 15 minutes
Eye protective is necessary!
Protective gloves are necesarry when filling the electrode! Do not touch the electrolyte with your
bare hands. When contact with the skin immediately clean with water at least for 15 minutes.
