8.5 Storage

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. Close the
filling hole and put the soaker bottle that contains the storage solution on the probe when not in use.
Refer to Figure 5. Keep the probe in a vertical position with the sensor and reference junction below
the liquid level in the soaker bottle. Add storage solution to the soaker bottle if necessary.
