MAINTENANCE

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.
•  If the junction becomes discolored, extract a fresh 1/8” 

section and trim off the soiled part.

CLEANING PROCEDURE

•  Soak in Hanna 

HI7061

 electrode cleaning solution for 

general use or 

HI700682

 cleaning solution for beer and 

wort for 20 minutes. Rinse with water. 

•  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 

procedures.

•  Electrode: Evaluate your electrode performance based on 

the 

Sensor check

 procedure on page 13.
