Attaching the Electrode Holder
to the Meter

Attaching the electrode holder to the meter 
facilitates one-hand operation. Attach two 
electrode holders if you have a separate electrode
and temperature probe.

1. 

Locate the slot on the left 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 

You can attach the electrode holder in different
positions. 

See figure

To attach a second electrode holder:

3. 

Align the flange of the second electrode holder
with the slot of the first holder. 

See figure

4. 

Slide the flange of the second holder into the
slot of the first holder until the tops of the hold-
ers are aligned and secure.

Inserting the Electrode into the Electrode Holder

Do not use excessive force when inserting electrodes into the holders.

1. 

Insert the pH electrode into the opening of the first holder until the top housing
of the electrode touches the top of the holder.

2. 

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.
