11.2 ORP Electrode Care and Maintenance
● Ensure that the ORP electrode is thoroughly washed with distilled water after each use.
● In aggressive chemicals, dirty or viscous solutions, and solutions with heavy metals or
proteins, take readings quickly and rinse electrode immediately after.
● If the electrode is not in use for long periods, store the electrode with a suitable electrode
storage solution.
CLEANING THE ELECTRODE:
Contamination of the sensor often results in slow response and inaccurate readings. If
necessary, clean the element by one of the following procedures:
Inorganic Deposits:
● Soak the ORP electrode in 0.1M HCl for 10 minutes.
● Remove and rinse with distilled water, then place in isopropyl alcohol for 5 minutes.
● Remove and rinse again, and soak in pH 4.01 buffer solution for 15 minutes.
Oil and Grease Films:
● Wash the electrode gently with detergent and water.
● Immerse the electrode in electrode storage solution for at least 30 minutes.
