1. Place a magnetic stirring bar in a titration cell and dispense the sample as follows:
• Add 10 mL of the sample (either milk, brine or degassed wine depending on the
area of application)
• Tomato sauces: Add 1 g of the sample dissolved in approximately 10 mL of
distilled water
2. Attach the titration cell to the magnetic stirrer.
3. Lower the electrode into the titration cell.
Hinweis: Make sure that the electrode cannot be damaged by the stirring bar or come into
contact with the bottom of the titration cell. Make sure the combined pH Electrode, including the
reference element porous pin is covered by sample.
