Refilling the Electrode

• To remove the electrode sleeve, carefully rotate and slide it off (A). Set it to one side.
Note: Handle the probe with care, the pH electrode stem is made of glass.
• Rinse off any traces of electrolyte gel from sleeve. Soak the electrode tip in
General purpose cleaning solution (or HI700661, HI700663, HI700664) for
20 minutes. Rinse with distilled or deionized water.
• Refill the reference well with
• Replace the sleeve. Ensure the O-ring is fixed inside the electrode. Rinse off excess gel
with distilled or deionized water.
• Shake the probe down gently to eliminate any trapped air bubbles.
• Soak the probe in HI70300

Storage

To ensure a quick response, the glass tip and junction should be kept hydrated.
When not in use, add a few drops of storage solution to the storage cap. If storage solution is not available, pH 4.01 or
pH 7.01 buffer can be used.
Note: Do not store the electrode in distilled or deionized water.
