4. Preparation Before Use
If it is first-time use or the tester hasn’t been used for a long time, pour some 3M KCL solution in
the probe cap (about 1/5 of the probe cap) and soak the probe for 15-30 minutes.
When not in use, we recommend store the pH probe in the storage 3M KCL solution in the probe
cap to keep the sensor’s accuracy. But even if stored dry, it won’t do any permanent damage to
the sensor. It will only temporarily cause the probe to lose its sensitivity, which can always be
restored by soaking in the storage solution.
