Field of application wine
This model is particularly suitable for measuring the sugar content in fruit. This is used to determine what alcohol content can be expected from the fruit. Likewise, the degree of ripeness of fruit (fructose), e.g. grapes etc. can be determined.

Main areas of application:

  • Agriculture: wine and fruit growing
  • Wine production
  • Must and alcohol production
