ELECTRODE MAINTENANCE
PREPARATION
• Remove the protective cap. Do not be alarmed if any
salt deposits are present. Rinse with water.
• Shake the electrode down as you would do with a
clinical thermometer to eliminate any air bubbles inside
the glass tip.
• If the glass tip and/or junction are dry, soak the electrode in
HI70300
Storage Solution for a minimum of 30 minutes.
• Rinse with water.
• Calibrate before using.
STORAGE
• To ensure a quick response, the glass tip and the junction
should be kept moist and not allowed to dry.
• Replace protective cap with a few drops of
HI70300
Storage Solution. Follow PREPARATION above before
taking measurements.
Note: Never store the electrode in distilled water.
PERIODIC MAINTENANCE
• Inspect the electrode for any scratches or cracks. If any
present, replace the electrode.
• Rinse off any salt deposits with water.
• Follow the STORAGE procedure above.
CLEANING PROCEDURE
• Remove the stainless steel blade.
• Soak in Hanna
HI7061
General Cleaning Solution or
HI700630
grease and fats acid cleaning solution for
20 minutes. Rinse well and calibrate before using.
• Soak the electrode in
HI70300
Storage Solution for a
minimum of 30 minutes. Rinse with water. Calibrate
before using.
TROUBLESHOOTING
• pH Meter: Follow the meter’s operating and calibration
