Vitamins, natural sugar and fruit pulp. Wonderful for your health, not so much for your pH measurement. Make sure to use an electrode with a fixed ground joint diaphragm. A ceramic pin diaphragm would quickly be blocked by such samples.
Measuring the pH of fruit or vegetable juices in the laboratory
is most comfortably done with the Metrohm 827 pH lab and
the Metrosensor
Unitrode.
Routine measurements At the plant, the pH of vegetable or
fruit juices can quickly and comfortably be measured using the portable Metrohm 826 pH mobile plus a Metrosensor Unitrode.
Precision measurements If you need an even higher precision
for your plant measurements and you want to take advantage of Metrohm's
unique electrode check, issue reports and reproducible measuring
methods,
you should opt for the Metrohm 780 pH Meter and a Metrosensor Unitrode.
