Attaching the Electrode Holder to the Meter
The waterproof pH 300/310 handheld meter comes complete with two
electrode holders. They are designed to facilitate one-hand operation.
Attach two electrode holders if you have a separate electrode and
temperature probe. Care must always be taken to avoid use of excessive
force in the process of attaching these components.
1.
Locate the slot on the right-hand side of the meter.
2. Gently slide the flange of the
holder into the slot on the
meter. Make sure the holder is
secured properly into the slot.
See figure 5.
3. You can attach the electrode holder in different
positions. See figure 6.
To attach a second electrode holder:
4. Align the flange of the second electrode holder with
the slot of the first holder.
5.
Slide the flange of the second holder into the slot of the
first holder until the tops of the holders are aligned and
secure. See figure 7.

Inserting the Electrode into the
Electrode Holder
Do not use excessive force when inserting electrodes into the
holders.
Insert the pH electrode into the opening of the first holder until
the top housing of the electrode touches the top of the holder.
If you are using a separate temperature probe, insert the probe into the opening of the second holder
until the ridge on the housing touches the top of the holder.
NOTE: The holder is designed for probes 12 mm in diameter. Electrodes larger than
12 mm may not fit in the holder. Forcing the electrode into the opening may
damage the holder or your electrode.
