ELECTRODE CONDITIONING AND MAINTENANCE
Instruction for Application Cleaning Solution
1. Add in a beaker about 50 ‑ 75 mL (or minimum to cover the electrode junction) one of the
following cleaning solution:
• Cleaning and Disinfection Solution for Dairy Products (
HI70641
);
• Cleaning and Disinfection Solution for Yogurt Products (
HI70643
);
• Acid Cleaning Solution for Meat, Grease and Fats (
HI70630
);
• Cleaning Solution for Cheese Deposits (
HI70642
);
• Alkaline Cleaning Solution for Meat, Grease and Fats (
HI70631
);
• Cleaning Solution for Milk Deposits (
HI70640
).
2. Soak the electrode for several minutes (5 ‑ 15) while moderately stirring the solution.
3. Remove the electrode from the cleaning solution and rinse it thoroughly with deionized water to
remove all traces of the cleaning solution.
4. After cleaning and rinsing it is preferable to store it in an electrolyte solution for about 1 hour.
5. Rinse the electrode thoroughly with deionized water and measure samples as usual.
Note: If the electrode response is slow or the electrode does not calibrate correctly, repeat the
cleaning procedure.
