Figure 1 Probe overview
1 Probe soaker bottle 4 Protective tape and filing-hole
2 Reference junction, glass bulb and temperature sensor 5 1 or 3 meter (3.28 or 9.84 ft) cable
3 Filling-hole cap 6 Probe soaker bottle holder
Preparation for use
Prepare the probe for use before calibration or sample measurement.
1. Turn the probe soaker bottle cap counter-clockwise to loosen the cap.
2. Remove the soaker bottle from the probe.
3. Rinse the reference junction and glass bulb with Ionic Strength Adjustor (ISA) rinse
solution (refer to Prepare the ISA rinse solution on page 11). Blot dry with a lint-free
cloth.
4. Remove the protective tape from the filling hole before initial use (refer to Figure 1
on page 2). Dispose of the protective tape.
5. Add filling solution to the probe as necessary (refer to Fill the probe on page 11).
The filling solution must be above the standard solution or sample level during
measurement (
Figure 2 ).
6. Make sure that the filling hole is open during measurement for the proper flow of the
filling solution.
Note: After long-term storage, the probe must be conditioned in 25 mL of 100 mg/L Na +
standard solution with the contents of one Sodium ISA powder pillow for at least 30 minutes
prior to use. If probe stabilization is slow after storage, condition the probe for up to one hour in
25 mL of 100 mg/L Na+ standard solution with the contents of one Sodium ISA pillow.
