To measure the pH of a sample of juice, wine, beer, kombucha. Packed per 20 strips with built-in colour scale! Reading per 0.2/0.3 pH.
- range 2.8-4.6 pH
- division 0,2/0,3 pH
What is pH?
pH
is the measurement of the concentration of free hydrogen ions in a
liquid. The pH of pure water is 7. Liquids with a larger concentration
of hydrogen ions than water are acid and have a pH value less than 7.
Liquids with a lower concentration of hydrogen ions on the other hand,
are base and have a pH value higher than 7. The pH scale runs from 1 to
14.
Can I measure the pH instead of the acidity of the must?
No!
In winemaking, the acidity is the representation of the amount of grams
of acid in your wine/juice, usually expressed in grams of tartaric acid
per litre. This can only be measured with a special indicating solution
like Vinoferm® blue indicator. You can, however, use a pH-meter in
combination with the blue indicator: instead of adding blue indicator
until the colour turns blue, add blue indicator until a pH of 7.00 is
obtained. This method is more accurate and gives better readings for,
amongst other things, red juices! The combination pH-meter, blue
indicator and an automatic burette is a professional set-up for
accurately measuring acidity.
