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 bulb. 

•  If the bulb 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 bulb 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

•  Soak in Hanna 

HI7061

 General Cleaning Solution for 

20 minutes. Rinse well and calibrate before using. 

IMPORTANT

: After performing any of the cleaning 

procedures rinse the electrode thoroughly with distilled 
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.
