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 4. Make sure to use the correct filling solution (3 M KCl). Note: If the dispensing tip becomes clogged, remove the dispensing tip and soak the tip in warm water. -
Page 15: Storage
N O T I C E Probes can become permanently damaged if kept in a storage solution that is not specified by the manufacturer. Use only the specified storage solution (Hach pH electrode storage solution or 3 M KCl). Do not store the probe in deionized water or in samples of low ionic strength. For short-term storage, the probe can stay in the sample for a maximum of 2 hours if the sample pH is not high. -
