Calibration Verification: Verify calibration before testing patient samples using quality control materials.
Cleaning: Use appropriate cleaning solutions for protein removal (protease solution) or oil/grease removal (mild detergent); rinse thoroughly after cleaning.
Dehydration Prevention: If electrode shows sluggish response, check for dehydration; soak in storage solution for 24-48 hours and recalibrate.
Filling Solution (Refillable): Maintain fill solution level above sample level to maintain proper reference potential; use only recommended filling solution.
Training: Only trained laboratory personnel should handle and operate pH probes for clinical diagnostic applications.

2. FIRST AID MEASURES
