CARE AND MAINTENANCE
The electrode should be soaked for at least
30 minutes before first use, or any time it has
dried out. It is normal for white crystals to be
present on the cap or electrode assembly.
Always handle and store the electrode
with care.
• Do NOT touch, wipe or rub the glass bulb.
• The pH glass bulb must always be kept
moist. Place it in the protective storage bottle
whenever it is not in use.
• Rinse the electrode in deionized water, a
rinse solution, or tap water before each use.
• Rinse the electrode in deionized water
between measurements.
