pH Electrode Refilling (pH110/115 refillable electrode only)
The refillable electrode does not need to be detached from the body of the
ExStik
TM
in order to perform the refilling procedure. Refillable electrodes
(PH115) have a removable reference junction (slotted) and the word
REFILLABLE on the side of the electrode housing.
Removing the Reference Junction
The removal tool supplied with the PH113
Refill Kit is used to remove the reference
junction screw from the sensing surface of
the electrode. If the reference junction does
not have slots for the ‘teeth’ of the removal
tool to lock onto, the electrode is NOT
refillable.
Holding the electrode upside down, unscrew
and remove the reference junction using the removal tool.
Filling the Electrode
1. Once the reference junction is removed, gently shake out all of the older refill solution
from the electrode.
2. Fill the electrode cavity completely with the refill solution supplied in the Refill Kit.
3. Replace the reference junction using the removal/installation tool. (Spare junctions are provided
if needed).
Filling Solution
The supplied container includes 15ml of filling solution. There is enough solution for 4 to 5 refills.
Use only the supplied solution for refilling the electrode.
