8.2 Fill the probe
Add electrolyte filling solution to the probe regularly to make sure that the electrolyte flows from the
probe to the sample. Refer to
Figure 6 . Make sure to use the correct filling solution (saturated KCl).
Note: If the dispensing tip becomes clogged, remove the dispensing tip and soak the tip in warm water. Then, fully
dry and assemble the tip again.
Figure 6 Fill the probe
8.3 Add KCl crystals to the probe
The filling solution in the probe contains crystals of potassium chloride (KCl) that keeps the filling
solution saturated with KCl. When the sample temperature is more than 60 °C (140 °F), more
crystals are necessary to keep the solution saturated with KCl. Add more KCl crystals when the level
of crystals above the glass bulb is less than 0.5 cm (0.2 in.), or when the sample temperature is more
than 60 °C (140 °F). Refer to
Figure 7 and Table 2 for preparation. Mix some of the filling solution
with the crystals to help move the crystals through the filling hole. Refer to Figure 8 .
