Storage
For the best probe performance, do not let the reference junction dry out.
Short-term storage
1. Put the filling-hole cap in the filling hole (
on page 2).
2. Store the probe in a 25 mL of 100 mg/L Na+ standard solution with one Sodium Ionic
Strength Adjustor (ISA) powder pillow (0.4 g).
Long-term storage
1. Put the filling-hole cap in the filling hole (refer to
on page 2).
2. Rinse the probe with ISA rinse solution (refer to
Prepare the ISA rinse solution
on page 11). Never rinse with deionized water. Dry the probe with a lint-free cloth.
3. Fill the probe soaker bottle half full with 0.02 M NH
4
Cl Electrode Filling Solution..
4. Loosen the soaker bottle cap and put the soaker bottle on the probe.
5. Turn the soaker bottle cap clockwise to tighten the soaker bottle cap.
6. Make sure that the solution in the soaker bottle completely covers the glass bulb and
reference junction holes.
7. Before use after long-term storage, condition the probe in 25 mL of 100 mg/L Na+
standard solution with one Sodium ISA pillow (0.4 g) for at least 8 hours.
