Hach-Lange PHC28103 - Manual (Page 11)

Note: The probe can be stored in a sample for up to 2 hours if the sample pH is not high.
1. Put the filling-hole cap in the filling hole (refer to Figure 1 on page 2).
2. Rinse the probe with deionized water. Dry the probe with a lint-free cloth.
3. Fill the probe soaker bottle half full with 2.44 M KCl 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.
If the glass bulb becomes dry:
1. Soak the probe tip in the 4.01, 7.00 and 10.01 buffers each for 5 minutes.
2. Rinse the probe with deionized water. Blot dry with a lint-free cloth.
3. Calibrate the probe.
