Aside from the effective techniques of transformation, wine quality strictly depends upon the quality of grapes used. The grapes must be selected and evaluated on the basis of precise and reliable analyses carried out immediately and automatically under the supplier's watchful eye. The result of the Maselli Company's 40 years of experience in analysis and titration instrumentation is the Multiparametric Station which performs:

Measurement of sugar content: the refractometric process is made by a long life LED light source, synthetic sapphire prism, CCD optical sensor to detect the image. The measurement is expressed in Brix, Babo, Baumé;it is possible to personally program all of the measurement ranges from the keyboard.

pH measurement is made by an industrial sensor with a polymeric electrode which does not require any maintenance and provides high accuracy in the measurement of "difficult" liquids such as musts.

Acid – Base Titration: a sample of known volume is obtained with a precise sampling method: a sodium hydroxide solution is dosed by a 10ml syringe with minimum dosages of 4 microlitres up until neutralization. The data is expressed, as is used, in gr/lt tartaric acid.
