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:
Ը
PC60-DE (Default pH/conductivity probe), PH60-DE (Regular pH probe for water solutions),
Ը
PH60S-DE (spear pH probe for food testing), PH60F-DE (flat pH probe for surface testing)
Ը
EC60-DE (conductivity probe)
Ը
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.
