SpecialSpecial requirements for the probe:

　　o pH electrode:Rinse with pure water before and after use, store as required in a protective liquid (e.g., 3M KCl solution).

　　o Electrochemical ProbeMay require specific electrolyte or polarization conditions.

　　o Optical Probe:Avoid fingerprints and scratches on the lens; pay attention to the direction of light.

　　o Contact displacement/pressure probe:Avoid overloading; be mindful of contact force and angle.
