Identifying the Individual Electrodes
The photograph below shows an AP-600. If you have purchased an alternative model, some of the
electrodes shown may differ.
1.
pH (shown) or ORP or combined pH/ORP Electrode (see notes
below).
2.
Turbidity Receiver Electrode. The polished, 4mm diameter centre
section is the lens.
3.
Dissolved Oxygen (DO) electrode. The clear plastic sheet stretched
across the tip is the membrane. DO NOT TOUCH!
4.
Turbidity Transmitter electrode. The domed, 4mm diameter section
is the lens.
5.
Replaceable DO Membrane Cap.
6.
Electrical Conductivity (EC) sensing contacts.
Keeping the pH/ORP Electrode Moist
It is very important that the pH, ORP or combined pH/ORP electrode is kept moist when not in use. This is
achieved by always fitting the Storage Cap, which incorporates a sponge that should be soaked in SS-
25 Electrode Storage Solution. A 25mL bottle of this solution is supplied.
The sponge within the storage cap should be moistened with a few drops of pH/ORP Electrode Storage
Solution each time it is removed and replaced.
