Probe Care & Maintenance Tips
Proper probe care extends the life of your MW101 and keeps readings accurate. Follow these best practices:
Storage: Keep the probe hydrated in storage solution MA9015 or calibration buffer. Never store in tap water or DI water — this damages probe sensitivity.
Cleaning: Soak the electrode regularly in cleaning solution MA9016 to remove residue and prevent junction clogging, especially after testing organic samples.
Calibration: Calibrate regularly, after cleaning, and after extended storage to maintain accuracy.
Pro tip: Add the Milwaukee pH Maintenance Kit (PH-Main) to your order to clean and condition the electrode before first use.
