16. Probe Replacement
To replace a probe:
1) Take off the probe cap; 2) Screw off the probe ring 3) Unplug the probe; 4)
Plug in the new replacement probe (pay attention to the probe’s position); 5)
Screw on the probe ring tightly. Soak the probe in 3M KCL for 5-15 minutes.
Then perform calibration before testing.
The replacement probes that are compatible with PC60-Z are:
•
PC60-DE (Default pH/cond. Probe),
•
PH60-DE (Regular pH glass bulb probe), PH60S-DE (Spear pH
probe for solids/semi-solids pH testing), PH60F-DE (Flat pH probe for surface pH testing),
•
EC60-DE (Conductivity probe)
•
ORP60-DA (ORP Probe).
*Probes don’t last forever. Every probe will eventually age and fail even if you don't use it that often.
The typical service life of Apera probes is 12-24 months depending on the frequency of usage and
how well you keep it clean and properly stored. We recommend replacing your probe every 1 to 2
years to ensure the best performance.
