10. Tighten the electrode cap onto the body and fill elec-
trode body until fill solution volume is just below fill
hole.
11. Position electrode in a Hanna HI 76404 electrode
holder (or equivalent) and connect plug to meter.

•
Connect sensors to pH/mV/ISE meter.
•
Place meter in mV mode.
•
Place 100 mL of deionized water into a beaker with
stir bar.
•
Place the electrodes into prepared sample.
•
Add 1 mL of a standard (0.1 M or 1000 ppm stan-
dard) to beaker. Record the mV value when stable.
•
Add an additional 10 mL of standard to the solution.
Record the mV when reading has
9. Holding the body of the electrode gently press upper
cap with your thumb. This permits the fill solution to
drain out of the body. Release cap and verify elec-
trode returns to its original position (you may need to
gently assist for this to occur).
