6. Replacing the pH electrode
Fig. 12 pH sensor and holder assembly
During transportation the pH sensor holder and sensor itself are packed
separately. In order to place it in working position, follow the sequence:
1. Using the screws, attach the pH sensor holder on the side of the analyser
as shown on Fig. 12.
2. Tighten the screws.
3. Put the electrode in the holder.
Follow the instructions for рН measuring.
7. PH measuring.
Measuring pH is an additional feature of the analyser and is optional.
Remove the protective rubber cap of the pH electrode. Take care to handle it
appropriate in order not to be damaged. Use de-ionized or distilled water to
rinse the electrode before usage. Fill in the sample holder with milk, put it in
the recess of the analyser and dip the pH electrode into the milk sample,
ensuring complete dip of the electrode in the sample. Stir gently for
homogenization of the sample.
Measuring can be done in two modes:
Off line by starting the menu pH & Co Meter | Measuring, when the
analyser works only as a pH meter.
