MAINTENANCE
PROBE STORAGE
REGULAR USAGE (DAILY OR WEEKLY)
Make sure the probe cap stays moist by closing
the probe when not in use.
LONG-TERM STORAGE
Add 3M KCL solution or pH 4.00 buffer solution
up to one quarter of the probe cap. Close the
probe cap tightly to store the probe in it.
If the probe is dried out, or if the probe's
response is much slower than usual, soak
the probe in 3M KCL soaking solution for
about 2 hours to restore its sensitivity.
